Thanks for the report, Jack.

I suspect this is related to bin/125185, which involved csh improperly 
messing with global state in a vfork'ed subshell.  Note that for both the 
present bug and 125185, the crash does not occur if csh is run with -F to 
use fork() instead of vfork().

nate@vulcan:/usr/home/nate$ csh
%"`"
Unmatched `.
Segmentation fault: 11 (core dumped)
nate@vulcan:/usr/home/nate$ csh -F
%"`"
Unmatched `.
%

I'll repeat my recommendation from 125185 that -F be made the default, so 
that vfork() is not used.

I doubt that this bug is amd64 specific but don't have another machine to 
make sure at the moment.  Probably it should be reclassified as "bin". 
It's also present in 7.0-RELEASE, by the way.

It's also present in 7.1-PRERELEASE/i386 but not in 6.3/i386

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.

This is incorporated into bin/129405.
