Hi all,
I have a G5 running stable/13. A couple of weeks ago, I did the regular
fetch, rebuild world, and reinstall... and almost all new userland binaries
started crashing.I thought the crashes would be due to a kernel/userland
incompatibility, but after rebooting with the new kernel, the problem
persisted.
It took me some effort to recover the machine into a usable state. I had to
revert the source tree to right before clang was updated to 12.0.1 on June
13th, as I think this is the problematic change, and rebuild + reinstall
from there.
I just updated the tree again to the most recent stable/13, done another
buildworld, and I have confirmed that most binaries are still broken in the
same way:
root@g5:/usr/obj/usr/src/powerpc.powerpc64 # ./bin/echo/echo
Segmentation fault (core dumped)
root@g5:/usr/obj/usr/src/powerpc.powerpc64 # gdb ./bin/echo/echo
...

(gdb)
The stacktraces I get out of the binaries are meaningless. You can see echo
crashing upon entering main. ls crashes on a local variable assignment. But
cp gets further along and is able to print its own usage message before
crashing.
Anybody knows what might be going on?
Thanks!
