Hmm. Does resulting core dump "looks" ok? it should be elf file of
size 1MB or more. Do i remember correctly that gdb crashes even on
coredump created by simple { int* x=0; *x=1; } program?

this should be fine.

I haven't changed anything in dumper since 1.3.6-6, so it's probably
won't help.

you can wrap dumper.exe into dumper.cmd file and call it with
debugging output to see what's going on.

anyway, i believe that even if dumper creates wrong dump file, gdb
shouldn't crash on it. Is it possible for you to send me by private
mail your foo.exe.core.bz2 (along with debugging output from
dumper.exe, if possible), so i could take a look at them?
