This still the case? Tested on ppcp-4as.lab.boston.redhat.com: * on RHEL4U3 its native gdb-6.3.0.0-1.132.EL4.ppc64 * on the current RawHide (chrooted there, so on kernel-2.6.9-34.EL.ppc64) its native gdb-6.5-8.fc6.ppc64 * on the current RawHide (chrooted there, so on kernel-2.6.9-34.EL.ppc64) the downloaded http://armstrong.rhts.boston.redhat.com/distros/nightly/rawhide-20060923/development/ppc64/os/Fedora/RPMS/gdb-6.5-8.fc6.ppc64.rpm (as current RawHide does not contain gdb.ppc64 - Bug 206488) In all the cases not reproducible for gdb.ppc6 -> /bin/echo (ppc), expecting some other system component (already fixed nowadays) dependency there. Please reopen if some reason still exists. |
