Hi Ruben,
Thanks for pointing this out, the problem is indeed that libstdc++ is
linked to the dynamic ligcc while the program (as above) links to the
static version of libgcc. There are two seperate copies of libgcc that do
not share exception information resulting in uncaught exception.

Hi Tai,
Thanks for looking into this. You are correct the right frontend should be
used, however this isn't the root of the problem.
It works since g++ defaults to -shared-libgcc while gcc defaults to
-static-libgcc.
If you force g++ to static link libgcc, the exception is still uncaught:
g++ -
Hi Yaron,
I can't reproduce your reported issue by using proper frontends. You
shouldn't use gcc frontend. Instead use g++. Later automatically
adds proper link-libraries for c++ automatically. So you don't need
to add -lstdc++ manual.
By using 'g++ -o a a.cpp && ./a' it works for me as expec
Using i686-4.9.1-release-win32-dwarf-rt_v3-rev0.7z on Windows 7 64 bit,
with this simple code:

void t() { stype s; throw 1; }
int main() {
try { t(); }
catch (...) { puts("Caught"); }
}
When compiling with:
gcc a.cpp -lstdc++ & a
the exception is
