I think there is a bug in FVWM's parameter expansion.
FVWM crashes with a simple command such as:
Echo $[0]
Is this supposed to be fixed? FVWM still crashes on my system
when I type "Echo $[0]" in FvwmConsole.
I am using current version of CVS.
There is something wrong with __eae_parse_range. I'm not that good on
sscanf, but I think that it will match "%u-%n" even for "0" and return a
good number, meaning that n will have a random value.
Yes, one big problem is that %n may or may not increase the return
code by one, so if
rc = scanf(..., "%u-%n", ...);
returns one, this can mean is parsed just the integer and stopped,
or it parsed the integer, found a '-' and assigned the %n too.
Fixed.
sscanf seems to not be very restrictive when it comes to unsigned
integers. It seems as if it accepts signed integers as well. At least
$[-1] hang fvwm now.
