mc-light with tcsh receives segfault

[Jeff Tipton]

Hi,

My mc-light doesn't work with tcsh. When I try to launch it:
 >mc
Segmentation fault (core dumped)

 >uname -a

It works with sh and csh but doesn't with tcsh. Actually, it even works 
within tcsh, if the SHELL variable is arbitrarily set to /bin/csh. 
Doesn't matter whether root or a regular user. Any ideas of what might 
be wrong?
