68 return ts_info(ts)->next_copy != ts;
I don't replicate this assertion.
Interestingly, I replicate a different assertion:
qemu-system-ppc: ../qemu/tcg/tcg.c:1210: tcg_temp_alloc: Assertion `n <
512'
failed.
Aborted (core dumped)
What compiler version(s) are you guys using?
With --enable-debug (that I don't normally use because it makes PPC emulation
too slow) I get the same assertion:
qemu-system-ppc: ../tcg/tcg.c:1210: tcg_temp_alloc: Assertion `n < 512'
failed.

Previous one was when configuring without --enable-debug, so maybe it depends
on compiler flags (-O2 vs. -O0).
