(This is the reply to a report about gcc-programs crashing after allocating
 both DOS and standard memory. It concerns go32 1.11.maint5)

Hi

I experienced the same problem lately. There is a bug in go32, in valloc.c.
I have fixed this and sent this fix to DJ, but I didn`t get the confirmation,
so I send it to you.
The base memory is allocated, but the same pages are reallocated again for
protected mode program.
