    Hi Matus, Thanks for filing the bug. I just recently checked in a fix for what you've hit. I believe it should be expected in VS2017 15.7. The root of it is that sometimes we improperly track EH information when dealing with initializer lists in calls (that's the { ... } in the parameter to ProcessDataPair). Probably the least invasive work-around would be to construct that std::pair manually using the () constructor form, rather than the {} form.

    Thanks,

    Aaron Gorenstein

    Hello Aaron

    Thank you for your help, and for the great work you guys do with Visual Studio. I already worked around the bug similarly to what you say, I just reported it so you know about it and can fix it.
