>Description:
With a system built from Jan. 11 source (after both of the powerpc
dynamic linking fixes) I got a SIGILL-induced core dump from /bin/sh
while building KDE3 from pkgsrc. I occasionally find that a daemon
or two has died, leaving a core dump in /.

 Something is telling porkies in that back trace.
 get_alias_text() is a small routine that is only called during
 some (obscure) command line edit actions.  It isn't recursive.

 I'd do an 'nm -n sh' and sort out the correct symbols for the
 return addresses ('objdump -d sh' might help validate them as well).

 Just realised: The problem with the backtrace is that /bin/sh
 has been stripped, so the only symbols available are those in
 the dynamic linker symbol table...

 If you built /bin/sh from source you ought to have the unstripped
 binary in the obj directory.
 Try pointing gdb at that file instead.

Since powerpc moved to secureplt, the PLT is now read-only and doesn't require
cache synchronization.
