Andrew Gallatin pointed out that same thing. It seems the 'J' option is what
is causing the crash. That (I think?) makes this a tcsh bug. I'll submit a
problem
report to Christos (anyone have his address? Not readily findable at
www.tcsh.org).
In the interim (before he has a chance to look over the problem and offer a
correction)
would it be possible to stop defining SYSMALLOC? I'll submit a PR for it if
you
believe thats appropriate.
