[Cgdb-devel] Crash

[Peter K. <pe...@ko...>]

I just updated to this mornings CVS and I got a crash when I try to set
a break point:

#0  0x08051fef in tgdb_append_command (com=0xbffff500, new_header=BREAKPOINTS_END, buf=0x0, buf2=0x0, buf3=0x0) at ../../tgdb/lib/types.c:85
85         (*com)[command_cur_size] = xmalloc(sizeof(struct Command));

backtrace:

It seems as though the com structure got screwed up some how.
