Random Signal 11 Exception running under Cygwin

I'm getting occasional and apparently random Signal 11 (SEGV) exceptions 
while running under Cygwin.  

I'm doing a cross-build of Glibc and after running for a while (sometimes 
a long while) one of the programs executed by make gets an exception.
The stackdump looks like the following:

	Exception: STATUS_ACCESS_VIOLATION at eip=00000000
	eax=00000000 ebx=00000006 ecx=610956F8 edx=00000000 esi=610901EC edi=610901F4
	ebp=0241FE34 esp=0241FE18 program=C:\cygwin\bin\rm.exe
	cs=001B ds=0023 es=0023 fs=003B gs=0000 ss=0023
	Stack trace:
	Frame     Function  Args
	End of stack trace

Note that in this case, rm got the SEGV, other times it has been
cpp0, ld or mv.   

The problem is not reproducible -- running the same make a second time
will fail somewhere else.  I don't have copies of the stackdump from other
executions at hand, so I can't compare, but in each of them the stack
trace is empty.

Any suggestions on (1) what might be causing this, (2) how I can avoid
the problem, and/or (3) how I can fix it?

BTW, I'm running on NT2K with the latest version of Cygwin.
