heap errors when running in gdb

[Harold L Hunt II]

Kris,

You know, you bring up a good point.  I used to use gdb on Cygwin all 
the time for debugging both XWin.exe and non-X applications that I 
write.  However, gdb has been broken for me on Cygwin for months now; it 
never works properly anymore.  I think I recall CGF insisting that gdb 
works for him, so I must be doing something wrong.

I do recall getting the SIGTRAP errors, and I generally have to kill gdb 
via Task Manager anytime I try to use it, but I do not recall getting 
any HEAP errors.

I don't know what to tell you  :(
