hello pdp-ers, i'd been experiencing mysterious segfaults with one of my pdp patches and have finally narrowed it down to the pdp_text object.
when a text string of 12 characters is banged into pdp_text, pd will very likely segfault. other string lengths seem to be OK. i've attached an example patch and would really like it if others could try it and see if they have the same result - i only have one machine around that i can check it on. it may take 5 to 10 bangs of the fatal messages to kill it ...
this is with: pdp-0.12.2 pidip-0.12.6 and 0.12.9 imlib2-1.0.6-1 from .rpm pd-0.36 rh9
oh, on a related subject: has anyone made anything like a strlen external for pd? i searched pdb and found nothing ...
thanks, bill
