On 6 Dec 1998, with Subject: [Win95] vfork: No more processes
I posted to this list the following:

I've tried any and all versions and compiles of 'make' that I
can find... and it is still happening. Others may be referring
to this as the expect/make bug on Windows 95.

I have ruled out hardware problems. All I know is that every
time 'make' reaps a dead child, 'make' causes what Win95
calls an "invalid page fault". Usually, 'make' crashes, but
sometimes Win95 kills a child and 'make' continues to run for
a little while before it happens again and 'make' crashes.
It is a horrible picture, what-with-all the crashes, faults,
bugs, and dead children spread all over everywhere. :-)
BTW, the Santa Claus Edition (SCE), a.k.a. 21.0 (0.7/1/1), of
the cygwin1.dll does not help any with this problem.

Any insights at all will be very appreciated. If this is being
discussed on the developers' list, please let us know.
This is a long post, sorry, but following is new information.
I've never used 'gdb' before now but if there's anything else
that I can provide that would help, please let me know. I'm
not a programmer so most of the following does not mean a lot
to me. Any explanations that anyone can provide about what is
happening will also be appreciated.
