  go32-v2 prints :

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.
DPMI memory available: 12852 Kb
DPMI swap space available: 116328 Kb

  and the command line invoked for the compilation is 

               gcc -o t t.c

  with <size> >= 4194304 you get the following message : 

c:/djgpp2/tmp\ccxaaaaa: could not read symbols: Bad value

I may send you the compiled fine with djgpp v1 and -O2 optimization, or with
djgpp v2 and no optimization but which crash the system with no message
with djgpp v2 and -O2. It seems to me rather difficult in this case to localize
the bug.
I am a fanatic user of djgpp since 2 years and use it to run on DOS platforms
fortran programs that where developped on Unix workstations.
