[PD] how to debug?

[Smoerk]

hello,

my pd (0.35 / linux) crashes or freezes sometimes. Propably it is one of
the externals I compiled, but I cannot figure out which one. Is there
some possibility to compile pd and the externals with debug options or
get traceback or some message why it crashes?

Now I can just guess which external it is and then I could write the
author "I believe your external is maybe responsible for crashing my pd,
but I'm not sure and I cannot give you any traces". ;)
