[Mingw-users] Cannot propagate exceptions - libstdc++-6.dll error

[michael k. <ko...@gm...>]

Hello.
I throw my custom class inherited from std::exception from within my 
DLL, and it makes Windows popup the error message saying that 
libstdc++-6.dll caused an error, and my application will be closed.
I use the latest MinGW base:
binutils-2.20.51-1-mingw32-bin.tar.lzma
gcc-c++-4.5.0-1-mingw32-bin.tar.lzma
gcc-core-4.5.0-1-mingw32-bin.tar.lzma
install.sh
libgcc-4.5.0-1-mingw32-dll-1.tar.lzma
libgmp-5.0.1-1-mingw32-dll-10.tar.lzma
libmpc-0.8.1-1-mingw32-dll-2.tar.lzma
libmpfr-2.4.1-1-mingw32-dll-1.tar.lzma
libpthread-2.8.0-3-mingw32-dll-2.tar.lzma
libstdc++-4.5.0-1-mingw32-dll-6.tar.lzma
make-3.82-1-mingw32-bin.tar.lzma
mingwrt-3.18-mingw32-dev.tar.gz
mingwrt-3.18-mingw32-dll.tar.gz
w32api-3.14-mingw32-dev.tar.gz

Any help?

I probably won't be of much help anyway, as I lack the technical
knowledge to help you, but I'll say this so others might be able to
help you out.

It's good to know what versions of everything you use, but a minimal
sample which does nothing but throw a custom class together with that
custom class. Additionally, you might provide information about why
you think this is a mingw-related issue - does the code work on gcc,
did you try it on any other compiler, etc.

It's not that people don't want to help you if you don't provide
enough information (alright, sometimes there's a bit of that too) but
it's that they can't.

Ok, i found out it was my mistake. Within the exception class i was 
throwing i did smth like std::string = null_c_string.
Thanks for help, you made me finally debug this thing.
