Segmentation fault on Modules-3.1.0b in tcsh

[Hon-Chi N. <hon...@my...>]

Hi

Has anyone encountered "Segmentation fault" error when running "module"
command of modules-3.1.0b on tcsh or csh?  Specifically, "module unload" and
"module list"?

The "module" command runs fine most of the time.  What I have noticed is if
I ran "module unload" for once or twice, it started to give "Segmentation
fault" errors on subsequent "module unload" & "module list" commands.

However, it rarely gives error on "module avail", "module whatis", "module
help", "module display" & "module load" commands.

In addition, it doesn't always fail on the same module command, as depending
on the previous module commands executed.

  % module unload gcc
  Segmentation fault

  % module list
  Currently Loaded Modulefiles:
  Segmentation fault

I also tried to use --verbose option for module, but it didn't get any
additional message before "Segmentation fault" error message.

I only encountered the "Segmentation fault" error on tcsh and csh, but I
can't duplicate it under bash.

I ran it on tcsh 6.10.  BTW, I believe my tcsh 6.10 is stable as I've been
using it for the last 2 months without problem, except the above.  And I
also duplicate the problem on tcsh 6.09, which has been running without
problem for more than 1 year.  I can also duplicate the problem on Solaris
/bin/csh.

I configured my modules-3.1.0b with default options except
    --prefix=
    --with-module-path=
    --with-version-path=
    --with-tcl-libraries=
    --with-tcl-include=

I built it using gcc 2.95.2 and linked it to Tcl 8.3.2 on Solaris 2.7.

Is it a bug in modules-3.1.0, or is it caused by user error?  If it's user
error, what are the possible mistakes I made that might lead to it?

Thanks.  Your help is highly appreciated.
