I'm fairly certain it is a tcsh problem.  I rebuilt it with -g,
and it seems to crash in a call to wcslen, with a NULL parameter.
(gdb) target core tcsh.core
Core was generated by `tcsh'.
Program terminated with signal 11, Segmentation fault.
#0  0x080a0182 in wcslen ()

Also, I compiled version 6.14.00 on the exact same system, and
that version does not segfault on !$:h history substitutions.
I'd say it's a tcsh 6.15.00 problem.
