I think this explains the crash, then. I didn't know about this EMM386
problem, but it certainly fits the symptoms. So, FED tries to blame
libc, but libc passes the problem on to EMM386, and, surprise! It 
turns out that Microsoft are at fault, yet again :-)

There is no particular need to run EMM386 these days except when you
actually want EMS memory, so it shouldn't do any harm to take it out
of your config.sys.
