That patches forces to use __builtin___clear_cache() from gcc 4.3 . Your
compiler might be older than the debian compiler, and that function might be
unimplemented for ppc. Could you check your and debian compiler version
numbers? Perhaps we need another #elif check for ppc systems.
Regards,
Another idea just came to my mind. This issue could be cache flush issue, since
the CPU executes instructions from the instruction cache, while gdb prints
instructions from the data cache.
In this patch cache flush changed by Tavian Barnes' request:

Just asking :) Yes, SIGILL should be precise on all cpus.

[ sane instructions according to gdb
Hi,
I've had the following bug report submitted; if the submitter is correct
(which seems likely, but I don't have a G4 powerpc box to test on), then
the jit code in 8.39 is using G5 instructions inappropriately (where the
8.38 code didn't).
Obviously, I could just disable jit for this
