Internal compiler error in VS15.5
I have another internal compiler error. No idea, if this information helps:
2>xxx : fatal error C1001: An internal error has occurred in the compiler.
2>(compiler file 'f:\dd\vctools\compiler\utc\src\p2\main.c', line 258)
2> To work around this problem, try simplifying or changing the program near the locations listed above.

Hi Markus, thanks for filing this and the other things you've found with the 15.5 release, we're really glad you're taking the time.
Unfortunately for this bug, this information isn't quite enough for us to investigate. It looks like it's happening during the linking phase -- do you think you could make a link-repro, as explained here? aka.ms/compilerbug
I understand if it's too sensitive to share a repro like that. Please feel free to email (aargor) or reply here to discuss ways of getting a repro. Of course if you can come up with a minimal repro, all the better :).
I see someone posted a comment with an attachment possibly with the same issue, but I'm afraid I don't see the attachment on my end.
Thanks again,

Hello Aaron. Not Markus, but when I've voted up this issue I've added a simple repro case as an attachment where the issue appeared to me (and went away If I commented single line). Not sure if you can see it (I'm not sure how to access it now myself ;P).
Ah, a colleague helped me find the attachments, yes, I see bug.cpp, thanks! Unfortunately I can't repro the bug -- what were the compiler/linker flags? I'll be able to investigate more tomorrow either way.
Aaron,
I had provided a repro for https://developercommunity.visualstudio.com/content/problem/3436/internal-compiler-error.html but this is still under investigation for over a year.
I use a static library and multiple projects for executables that link this static library using LTCG. The internal error is only for a build after changes in the library and only for a few projects. Until 15.5 it was only for one project (reported for RC), now also for a second. If I use rebuild all or clean before building everything works. The problem is only for x64 not for x86.
I am not able to come with a minimal repro, but I did send you a link-repro by e-mail now.
(Our automation makes sure we comment after changing your bug's state to "Need More Info", but I wrote all the details in that earlier comment. Whoops, please ignore this comment :))

Hi Callin,
Thanks for attaching a repro. It's actually a different issue than the one Markus has hit. I've filed a bug internally and shared that it's customer-reported. Feel free to submit a new issue here with the same attachment so you'd get updated on when it's fixed.
Hi everyone,
First, thanks again Markus, both bugs you've filed are being looked at by the right developer, using the repros you'd newly-provided in our email exchange.
Second, thanks Малютин Данила Павлович and callin.mayes@oou.us for reporting possibly-similar issues. I'd recommend that you (and anyone else reading this) file new devcommunity issues for the crashes you're facing. I totally understand that the crash reports look the same, but it's probably the case you've actually hit different bugs.
Usually if two different code-bases cause the compiler to crash, there are really two different compiler bugs being revealed. Because we want to make sure we fix all these things, it's a lot easier to track when you file your own issues rather than comment on what is actually a different issue. This may also help track things for you: when we mark this bug fixed, we'll be talking about the one Markus reported, not the bug Callin reported, for instance. I'll be following up with their comments individually.
Thanks again everyone for being proactive in filing this bug reports!
Hi Aaron,
my bug report https://developercommunity.visualstudio.com/content/problem/161093/vs-155-linker-stuck.html
was marked as 'identical' to this one. This doesn't seem consistent with what you wrote above..
Thanks
I see that issue as well. The corresponding bug we created for your feedback item was fixed, I believe Chris just linked it to the wrong developer community thread: https://developercommunity.visualstudio.com/content/problem/148946/infinite-compilation-time-on-blake2cpp.html is probably one that he meant.
Hi Markus,
Thanks for the bug report, and providing the link repros. I've looked into both bugs/repros you submitted, and I confirm it's a compiler bug in incremental LTCG feature, and they're the same issue. We have a fix in our development branch for this issue. We'll get the fix out in upcoming release - will let you know once we know which release will have the fix.
To workaround the issue for now, you can use "Rebuild" from IDE instead of "Build" for this project.
Thanks.
I'm getting what appears to be the exact same error.For me it happens when I switch float codegen from precise to fast.The line it refers to is simply a bunch of float math (+ * / sqrtf), let me know if you the exact code.
Hi Wouter,
Thanks for thinking of submitting a bug -- please submit a separate issue. The crash-dump that Markus shared is extremely common across multiple, distinct bugs. By analogy, if a program crashes because of a null-deref, if you also hit another null-deref crash, it's not necessarily the same root cause.
Thanks,
Aaron
Thank you for your feedback! We have fixed the problem in an upcoming release. Thank you for helping us build a better Visual Studio!
The fix for this is now in our latest Visual Studio Preview release. If you'd like to try out the fix, you can access the preview build here: https://www.visualstudio.com/vs/preview
