With Pd-extended 0.42.5 and GEM 0.93.1. I have pthreadVC.dll in the /bin/ directory.
The following helpfiles, included with GEM, cause pd to crash:
pix_texture-help.pd pix_tIIR-help.pd pix_threshold-help.pd pix_texture-help.pd
There are probably more, but I haven't checked because there is only so much sadness I can handle in one night.
Pd crashes when trying to open the files by: *starting pd and navigating to the patches from the File menu *starting pd and trying to open the patches through the help browser *starting pd, creating a new patch, creating the object - e.g. [pix_texture] - and then right-clicking the object to open the help file
