Did you try to stubedit the debugger to a larger transfer buffer and/or 
larger stack size?

It most probably would make trouble with nested programs.  The transfer 
buffer is used to pass the environment to the child process when spawning 
sub-programs (like gcc does when it invokes the compiler passes).  If 
your environment is approaching 8K, you need to stibedit all the programs 
that can launch other programs to enlarge the transfer buffer.

I think dosexec.c in the library should test for such contingencies and 
print a message (I don't know off hand if it does now).
