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:

Using the attached source, I can do:

pd -lib libstdcpp -lib Gem -lib gridflow => no crash

Hope this helps others in a similar predicament.
