Hi all,
I think there is a bug in FVWM's parameter expansion.
FVWM crashes with a simple command such as:
Echo $[0]
I am looking at this problem in GDB. The variable 'm', suddenly has a
huge value when I reach line 918 of fvwm/expand.c:
if (input[m] == ']')
Then I get a SEGV because this is an illegal memory access.
Can anyone else confirm this problem?
I can'tr make it crash with just Echo $[0]. However the following make it
crash 100%:
AddToFunc TestFunc I Echo $[0]
TestFunc $[0]
I'll investigate that further after breakfast to see if it's the same crash,
or a different one.

Can you see if the fix I comitted for the above fixes your error as well?
It's possible that it's the same error if your strlen doesn't segfault on
NULL-input (and you did call Echo $[0] from within a funcion called by a
trailing space or something else to form an argument string with no
tokens).
