Description Jesse Keating 2008-02-22 13:10:11 UTC
This is an automatically filed bug for a failed rebuild attempt for GCC 4.3.


Please verify why this build failed and fix it.
Unknown exit code, check the failed task.

Comment 1 Mike Bonnet 2008-02-22 21:27:50 UTC
The i386 and x86_64 builds were hung during the lt-test-ptrace test.  By hung I
mean they were consuming 100% cpu time.  I'm attaching the output of a "ps -e -o
pid,ppid,pgid,cmd fww" to the bug.  The second to last entry (lt-test-ptrace)
was taking up most of the cpu time, with lt-test-ptrace-stepper occasionally
taking a few %.

Could this be a kernel/xen issue?  The builders are running 2.6.18-53.1.6.el5xen.

It is in fact a DUPLICATE of Bug 427850.
Going to fix it ASAP.
(No matter why the test(s) got locked up no test should be allowed to busy-loop

Committed to Rawhide:
* Sun Feb 24 2008 Jan Kratochvil <jan.kratochvil@redhat.com> -
- Abort the possibly hung up testcases after 120 seconds (BZ 427850, BZ 434147).

It works for me on F8, though.  The right way is to remove the testing from the
build and move it to a separate testing system (RHTS) as has been done with GDB.
