Pd doesn't write anything like a crash log, not even on request.
you'd have to do that manually.
the simplest way is to just redirect the stderr to a logfile:
$ pd -stderr 2>pd-$(date +%s).log
this is of course not a real crash-log, as it will just record whatever
is printed by Pd while it is operational. it might still help you
finding the cause of the problem.
also note, that depending on the verbosity this might grow quite big (if
Pd does NOT crash within a reasonable time).
another (more sophisticated) option would be to enable core-dumps and
inspect the one generated during the crash:
## enable core-dumps (in bash)
$ ulimit -c unlimited
## run Pd and wait till it crashes (creates a 'core' file)
$ pd CRASHPATCH.pd
## inspect the 'core' file generated by 'pd'
$ gdb pd core
