it seems like miller has fixed my buffer-overflow when taking the patch.
i have checked in the changes to the pdext-0-40 branch.

additionally it is also attached..
File Added: s_path.diff

IOhannes, Unless you feel like debugging this in Pd-0.40.3-extended, I
think I'll just remove the path portion of your patch from
Pd-0.40.3-extended, then deal with it in the next release cycle.

hmm, interestingly enough i was not able to crash a vanilla pd-0.41-4 with
about 49 paths

i suspect this to be a memory overflow where too many strings (paths) are
concatenated in a a string that cannot hold that many characters...

eighthave's comment on the mailinglist:

I was looking into this, it looks like it is caused by your Path/ 
Startup GUI patch, but I haven't pinned it down yet. Basically,  
builds from before I applied that patch don't crash, and builds after  
do crash on the Path menu.  It seems that the crash only happens when  
there are more than 30 or so elements in the Path menu, it does not  
crash with 0-10 elements.

hans' comment in the duplicate-bug#1953770

The Path... preferences pane causes Pd to crash if it has too many
elements
loaded in it. It seems to happen around 42 path elements.

i remember seen the same problem on XP autobuilds.

raised priority, as it is a crasher!
