Being on Debian myself, I tested your patch. It does not crash Pd,
however I also always get the glibc message, if I end Pd, and
sometimes Pd doesn't properly close itself. That is, only the GUI kind
of stops, the server keeps running until I Ctl-C it.  This doesn't
happen all the time, though. 

All this can be made to stop by not loading the xsample library, which
I don't use that often, so for me it's no big deal.
