You're absolutely right - crash is not specific enough. My apologies. To be specific, I have no logs that show any details of the "crash" as I call it - I can only tell you exactly what I observe.

1. I run my script (perl tests/propogate.t)
2. Script starts (output on STDOUT observed)
3. Entire display goes black
4. NVIDIA logo appears (using nvidia drivers)
5. Gnome login manager appears, prompting me to login
6. I login to Gnome again, open konsole and cd to devel directory again
7. Go back to 1 - process is 100% repeatable

A couple of notes:

• To find out that it was the call to touch() causing the crash, I reverted to previous rev of the file and re-added in lines one-by-one till the "crash" occurred
• This occurs on a quite-recent version of Perl (5.10.1)
• This happens not just on this machine, but on two other machines at exactly the same spot. (The only commonality I can find is all three use "name-brand" NVIDIA display drivers. All three run CentOS, but each a slightly different version. All CentOS versions > 5.1)

If it was just one machine, I might submit to the bad RAM theory - but three machines, all in the same spot? (Two desktops, one laptop.)
