	Hi

  Does anybody thought about writing core images when program gets some
signals (like in unix) ?  I dont't know if it't easy or difficult because
I have no experience with digging into DJGPP.  However, I had experience
with digging into core and I know how it's useful.  Of course, if the trouble
is caused by bad control structure, stack traceback and symify.exe is sufficient.
But when you have wild pointer jumping over multi-linked allocated data, it's
not enough.
 
  Answering on some questions:
- core should be dumped when program is bad, not operting system; when someone
 screws DOS it even can't flash num-lock light, we don't care writing images;
- writing cores should be at user option, not everyone wants to have them;
- gdb need not to create subprocess, it has only to look at dead program's state:
 local and global variables, dynamic data and unlucky instruction, then it needn't
 to restore full state of program - only memory;
- I think it would be also useful to bind one keystroke (say Ctl-Alt-Brk) to force
 program to dump core and terminate.

  Please, forgive me if I wrote stupid things. Just idea.
