I cannot reproduce this on a GNU/Linux machine that identifies itself
thusly:

  Linux fencepost 2.6.16.29-xen #1 SMP Wed Dec 6 07:32:36 EST 2006 x86_64 
GNU/Linux

Can you debug this?  The place where it crashes:

  0x081a2836 in Fsystem_process_attributes (pid=17936) at process.c:7417

is this (assuming you use a recent CVS):

   if (isspace (c) || c == '\\')

I wonder how it can crash.  But then optimized builds tend to lie
about line numbers.
