Hello Jonathan,
thanks for the propmt support. This is the output of valgrind when loading
the patch I was talking about:

Up to here the patch is on the screen with no issues, When I try to open
the main abstraction present in the patch, which contains the GUI, I get a
stack overflow:
==3875== Stack overflow in thread 1: can't grow stack to 0xffe801fa8
==3875== Can't extend stack to 0xffe801058 during signal delivery for
thread 1:
==3875== no stack segment
==3875==
==3875== Process terminating with default action of signal 11 (SIGSEGV)
==3875== Access not within mapped region at address 0xFFE801058
==3875== at 0x444938: ??? (in /opt/purr-data/bin/pd-l2ork)
==3875== If you believe this happened as a result of a stack
==3875== overflow in your program's main thread (unlikely but
==3875== possible), you can try to increase the size of the
==3875== main thread stack using the --main-stacksize= flag.
==3875== The main thread stack size used in this run was 8388608.

I can see an issue with a GEM library above, but this patch does not use
GEM.
This patch never caused issues since few releases ago (I'm not sure I
checked it with 2.3.3).
I quickly checked the windows version of purr-data 2.4.4 with same crash
results.
Just in case, the patch is available as part of my patch collection, but of
course I don't force anyone at debugging it :-)
https://sites.google.com/site/albertozin/Home/pd , it's the patch called
*~moduLaRe~*
Any feedback on how to debug further is welcome.
Thanks,
Alberto
