Comment 3 Jan Kratochvil 2008-04-14 00:07:42 UTC
It should be fixed in Rawhide/F9.
Upstream does not have this problem as it does not update / it has stale
information about the EXEC file being run which hurts support of PIEs
(Position-Independent-Executable) missing upstream.
The Fedora patch I put there for the EXEC file update was broken.

Comment 4 Jim Hayward 2008-04-14 04:44:48 UTC
I grabbed 6.8-2 from koji. Appears to be fixed here. Tested on i386. Not tested
on x86_64, but I was seeing the problem on both. Thanks.
