I have done this. It worked good and I got dbz.exe.core.

I have tried this and the complete bash shell died .

Thank you, objdump says now:
dbz.exe.core: file format elf32-i386
architecture: i386, flags 0x00000000:
But I get a message to stderr: no symbols.
If I call gdb with gdb --core=dbz.exe.core and I do 'info target', 'info threads'
and 'backtrace' and all worked. But I have not all symbols for the backtrace:
#0 0x77f782db in ?? ()
#1 0x77f04f37 in ?? ()
#2 0x6100bd88 in _size_of_stack_reserve__ ()
#3 0x6100c57c in _size_of_stack_reserve__ ()
#4 0x77fa7396 in ?? ()
#5 0x77f9926b in ?? ()
#6 0x77f86406 in ?? ()
#7 0x004010ca in main (argc=2, argv=0x1a020ca8) at dbz.c:16
#8 0x61003859 in _size_of_stack_reserve__ ()
#9 0x61003a3d in _size_of_stack_reserve__ ()
#10 0x61003a7c in _size_of_stack_reserve__ ()
#11 0x0040111f in cygwin_crt0 ()
I am sure I have compiled it with -g.
If I call gdb with gdb --core=dbz.exe.core dbz.exe I get a message from gdb:
core file may not match specified exec-file.
Is there something missing in the dumper or gdb implementation?
Is symbol writing not implemented in dumper?
