Description Arjan van de Ven 2004-12-30 14:51:53 UTC
my rpm test app uses threads to spawn off a lot of it's work.
In such threads I use popen() frequently, and system() occasionally.
On the RHEL3 8way machine, about 30 threads are used.

Symptom: system() returns -1 fairly frequently

Does not seem to reproduce on my fc3 dual machine at home

This turned out to be a bug (well, lots of bugs) in libmagic.so's compress.c.
