libstdc++ also needs to be built and linked in as dll.
Search mingw archive lists for other examples and approaches.

i'm passing --enable-shared to gcc's configure but it only
creates shared libgcc_s_1.dll. libstdc++ is still static.
should i applay some magic patch on the top of 4.4 to get more dlls?
> Search mingw archive lists for other examples and approaches.
i've found two interest examples:
[Mingw-users] DW2 EH works "sometimes"
http://marc.info/?l=mingw-users&m=114984388106110&w=4
[Mingw-w64-public] SEH doesn't work on mingw-w64
http://www.mail-archive.com/mingw-w64-public@lists.sourceforge.net/msg00150.html
the rest of googled threads are about patches already committed for 4.4.

adding try{throw 0;}catch(...){} to main() shows that dw2-exceptions
don't work at all, so it's not related to dll crossing.
new testcase attached.

AFAICT DW2 unwind has never worked on x86_64-mingw32, which is why Kai made
sjlj the default EH model for that target.

ok, with sjlj and shared libgcc exceptions seem to work across dlls.

This is right, that dw2 exception handling doesn't work for x64. As the x86 is
absolutely incompatible to the x64 exception handling, there is the support of
SEH2 unwind-data to be added. I begun already with support on gas to generate
the pdata/xdata data by pseudo-opcodes. I plan to support this feature for
4.6.x (and maybe a 4.5.x). So for now, just sjlj exception handling is possible
for x64 windows.
