I'm making a new version of my installation shown in Norway.
Unfortunately the same patch is no longer stable, it dies due to what
looks like a memory leak.
Here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.

Seems to me this is happening due to some list functions called by zexy?
I greped through all the zexy objects that output lists, and compared
those matches to my PD patches, and the results are not very telling.
tabdump seems the most likely cause, but I've used the same version in
other patches as many as 2,000,000 times, without noticing an issues.
I'm using zexy 2.1 from svn.
I just did an svn update and compiled a non-stripped zexy.
I'll post back if this issue is not solved.
Has anyone else come across this?
