[Qemu-devel] intermittent make check failure: "tcg_handle_interrupt: assertion failed: (qemu_mutex_iothread_locked())"

[Peter Maydell]

I got a make check failure on aarch64 host running a sparc64 test:


TEST: tests/prom-env-test... (pid=13573)
  /sparc64/prom-env/sun4u:                                             **
ERROR:/home/pm215/qemu/translate-common.c:34:tcg_handle_interrupt:

FAIL
GTester: last random seed: R02Sa5fa983185fe5e65cfb5b7fcb39ed3d1
(pid=13579)
FAIL: tests/prom-env-test

This is with commit 9514f2648ca05b3.

It didn't reproduce on a rerun of 'make check' and it didn't
look like the merge in question was particularly relevant to
the failure, so I went ahead and pushed it to master.

I'm (perhaps unfairly) assuming that this is fallout from MTTCG
landing. (prom-env-test is one of the handful of tests in
'make check' that actually runs TCG code.)
