Comment 1 Jan Kratochvil 2007-06-23 09:24:04 UTC
Probably the same reason is for:
FAIL: gdb.pie/attach.exp: (timeout) after attach3, exit


Comment 2 Jan Kratochvil 2008-01-14 10:34:35 UTC
This problem is no longer seen neither in Brew nor in RHTS, older logs were
deleted.  Expecting a consequence of the inappropriate and/or utrace-buggy
kernels in Brew but I did not check it more.
