Dear all,
I copied some code from here
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33903#c5 and removed those dl*
stuffs and tested it. But this piece of code only works on my linux.
I got this result with mingw-w64-gcc x86 version:
E:\Desktop>g++ -v
Thread model: win32
gcc version 4.9.0 20140218 (experimental) (i686-win32-sjlj, Built by
MinGW-W64 project)
E:\Desktop>g++ test.cpp -O0 -g -Wl,--wrap,__cxa_throw
E:\Desktop>gdb a
(gdb) r
Starting program: E:\Desktop\a.exe

And this result with x64 version:
E:\Desktop>g++ -v
Thread model: win32
gcc version 4.9.0 20140218 (experimental) (x86_64-win32-seh, Built by

Any suggestions?
