Description of problem:
With both 4.5.8-1 and 4.5.9-2.EL4 I'm seeing 'strace64 date' segfault. 'strace
date' completes successfully.
Version-Release number of selected component (if applicable):

'strace64 strace64 date' output
Has this ever worked? date is a 32-bit binary, right?
Yes, 'date' is a 32-bit binary:
# file `which date`
/bin/date: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV),
for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
I labelled it 'not a regression' during testing, so I'm not sure that it's ever
worked, but maybe something to look into.
It looks like another illustration for the problem I described in RH#173050.
ppc32 strace does not handle ppc64 binaries and ppc64 strace does not handle
ppc32 binaries. That's why there is an strace64 rpm on ppc64, so you can use
strace64 for 64-bit binaries and strace for 32-bit binaries.
