Description Arjan van de Ven 2004-12-30 09:51:53 EST
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

testcase program
in addition you need
devserv:~arjanv/testcase.tar.bz2
and potentially 
devserv:~arjanv/file-4.10-2.i386.rpm
(which comes from FC3)
Comment 2 Arjan van de Ven 2004-12-30 10:45:49 EST
the testcase.tar.bz needs to be untarred in /tmp fwiw
Comment 3 Jakub Jelinek 2004-12-31 11:23:15 EST
This turned out to be a bug (well, lots of bugs) in libmagic.so's compress.c.
