[PD] segmentation fault

[Miller Puckette]

Hmm... well, Pd almost never gives me segmentation faults (I use a linux
machine) but there are almost certainly bugs I don't know about.  Segmentation
faults can come from Pd or from external libraries.  The only way to
find out which is the culprit is to find some repeatable way of making Pd
"segfault" and report it to me or to the list so we can recreate the problem.

There are two ways I know of that you can cause Pd to fail.  One is to run
out of memory; for instance if you have 128 Meg of memory and try to load mor
than about 40meg of 16-bit samples to tables, Pd usually will crash.

Second, if you use any of the "data structure" objects such as "template"
and "pointer", closing patches can easily make Pd segfault.

Other than those caveats ,I don't know what you can do to make Pd fail...

cheers
