Hi,
I'd been having horrible issues with Pd crashing with a segfault in __cxa_allocate_exception() when using both Gem and GridFlow, preventing me using the Gem<=>GridFlow bridge:
pd -lib gridflow -lib Gem => no crash pd -lib Gem -lib gridflow => segfault
Turns out that it's a bug in the ATI OpenGL implementation, and the suggested workaround (to link libstdc++ before opengl libraries) works better than I had hoped:
http://wiki.fifengine.de/Segfault_in_cxa_allocate_exception#Workaround
Using the attached source, I can do:
pd -lib libstdcpp -lib Gem -lib gridflow => no crash
Hope this helps others in a similar predicament.
Claude
