RHEL got an update for ltrace that can run 32bit binaries under a 64bit OS:
It would be nice to have 0.3.36 under FC3 as well.
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
Since FC3 has reached the EOL phase, it's probably a good idea to close this
bug, too. FC4+ fix it.
