Hello!
> Confirmed with clang++ 8
Good!
Meanwhile i've tried to investigate it myself a bit and here's some more info:
1. With clang 8 __cxa_throw() ends up in Windows RaiseException(); with clang
5 it simply doesn't make it there. I guess there's some problem with
interpreting unwind info.

The problem maybe in ABI incompatibility with older C++ (not C++11-compliant)
run-time libraries:
In C++11 class inheritance for many standard exceptions has changed greatly, so
all the run-time
libraries must be recompiled to match the inheritance seen by the compiler in
the header files

Hello! I haven't upgraded for a while and today i finally decided to do so.
After rebuilding by project with clang++ 8.0 i found
out that try...catch construct doesn't work. The program just gets silently
aborted.
Switched back to old clang++ 5.0 and it works.
Also an old bug which i reported
10 matches
