 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.
