It is not possible.  SIGSEGV indicates that your program has violated
memory protection; it can be trapped but your program MUST exit after
the handler is called.

There is no safe way to recover from a SIGSEGV so the DPMI host won't
even try.

Please see the chapter of the DJGPP Frequently Asked Questions List on
debugging (chapter 12) for instructions on how to make sense of the
stack traceback that is printed when your program crashes, and how to
use the various debugging tools that come with DJGPP.
