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! Roland
