I have experienced exactly the same problem! On two different machines
running XP. But actually, I'm not sure this is due to the new DLL
version. It happens firts using an older version but the bugs disappered
strangly after a several usings. In an other hand, it happens on this
computer I am currently using since Windows asked me to change the
amount of virtual memory. I've tried to upgrade to the latest version
version but the problem still occurs each time I invoke a tcsh. The
amount of memory used by the tcsh process (visualized using windows task
manager) doesn't stop to grow! 

The very strange thing is that I launch tcsh with the -f option it works
very well (about 3000Kb used by the process). After that, if I do a
source /etc/csh.cshrc and/or source /etc/csh.login... it's still working
good.  So I have tried to remove all /etc/csh* and ~/.tcshrc or ./cshrc,
the behaviour is always the same: memory problem whithout the -f and no
problem at all with it. Using a simple .tcshrc containing only a: echo
allo produces this when using the -X option:
bash-2.05b$ tcsh -X
echo allo
allo
And the memory problem is still here...

Note that if I press CTRL-C few seconds after launching tcsh (no option)
it produces a usable tcsh shell, but the problem of memory allocation
reappears when exit is typed to terminate the shell process.
