The example program is part of my initial post.
(http://sourceware.org/ml/gdb/2005-04/msg00113.html)

For compiling it I simply did a
/path/to/my/x86_64-w64-mingw32-gcc.exe -g gdb_crash.c -o gdb_crash.exe

But the concrete example does not matter. Whichever program I compile 
variable viewing is totally broken for me (gcc 4.8.2 prelease 20130730 
with mingw-w64 runtime from 20130730) all with above error messages.

Thanks for your help. I hope this can be resolved soon. I would love to 
enrich my gdb with SEH2 unwinding!
