FVWM crashes with $[0]

[Scott Smedley]

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?

Scott. :)
