Has this ever worked?  date is a 32-bit binary, right?

Comment 3 Jay Turner 2005-04-25 08:03:53 UTC
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.

Comment 4 Dmitry V. Levin 2006-01-06 23:01:17 UTC
It looks like another illustration for the problem I described in RH#173050.

Comment 5 Roland McGrath 2006-01-12 10:21:08 UTC
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.
