I am trying to compile my C programs using DJGPP, but it (and the DOS

box) crashes with

  This program has performed an illegal operation and will be 

  terminated. Quit all programs, and then restart your computer.



  Details >>

    This program encountered a general protection exception 

    Fault location:        0117:114000

    Interrupts in service: None

The actual "fault location" varies each time I try it.

The same programs compile on gcc and proprietary compilers on other

platforms (SunOS, Solaris, SGI, DEC OSF). Can anyone tell me how to 

get around this problem? 



Here are some details the FAQ asks me to report:

go32/v2 version 2.0 built Jan 23 1996 22:03:02

Usage: go32 coff-image [args]

Rename this to go32.exe only if you need a go32 that can run v2 binaries

as well as v1 binaries (old makefiles).  Put ahead of the old go32 in

your PATH.
