I can compile a Linux kernel and there should be a h/w problem?

The compiler reports an ICE and just an ICE, with no other data.
Perhaps RHIDE cuts out important parts, but I could not reproduce the
ICE without using RHIDE. ( but I cannot write makefiles :( and I like
the RHIDE editor and debugger frontend )

I found out:
1) it cannot be a h/w problem because everything works when compiling
in Linux with GCC.
2) The RHIDE memory display decreases and stays at a lower value when
finished
3) The ICEs occur much more often when I restrict the DOSAPP's DPMI
memory to 64MB or lower
4) Sysmon32 always shows <10MB free memory and a >50MB disk cache.
Because I am using Windoze I never get more free memory.

But this looks interesting:


  #include <crt0.h>
  int _crt0_startup_flags = _CRT0_FLAG_UNIX_SBRK;

But I do not have the djgpp source to change this!
