iirc, i did run into crashes in similar situations, though i cannot
recall the exact details.

finally, i decided, that i never want any graphics to run in realtime,
risking a more likely freeze of the machine without any real gain,
whereas i almost always want audio to be realtime and also would like to
avoid graphics to interfere with audio whenever possible. 

since then i haven't used '-lib [Gem|pdp|gridflow]' and '-rt' in the
same instance of pd and could get rid of such nasty issues. in projects,
that use both, audio and video, i usually put all tilde and timing
objects into the audio (-rt, maybe -nogui) pd instance and the gui
stuff, video calculation and displaying into the video (-nrt) pd
instance. both talk over a network socket with each other.
