ah, it seems that passing NULL to strlen() (somehow nested in the Pd-function we call) triggers undefined behaviour, that's why it crashed for you but not for me.

Starting pd with : `pd -noprefs -lib pix_foo` works and I got in the console : `pix_foo: can't load library`
Starting pd with : `pd -noprefs -lib Gem:foo` works and I got in the console (after Gem loading message): `foo: can't load library`
