Hi,
on a Mac OS X (Intel) machine, I have the following weird problem:
calling the table method on a Proc::ProcessTable object creates a
segmentation fault some of the time, sometimes it works just fine.
This is illustrated in the attached test script. If I run it on the
Mac machine, I (sometimes) get the following:
trinidad:~ klink$ (for ((i=0; i<100; i=i+1)); do perl pt_bug.pl ; sleep
1; done)|wc -l
85
running it on a Linux machine (which uses perl 5.8.8 as well), I get the
expected "100", so apparently it does not crash there ...
Here is the uname:
Darwin trinidad.local 8.8.1 Darwin Kernel Version 8.8.1: Mon Sep 25 19:42:00 PDT 2006; root:xnu-792.13.8.obj~1/RELEASE_I386 i386 i386
