For aarch32 host i386 guest I got this failure on the
migration-test /i386/migration/multifd/tcp test:

*** Error in `i386-softmmu/qemu-system-i386': malloc(): smallbin
double linked list corrupted: 0x01b564b8 ***
qemu-system-i386: check_section_footer: Read section footer failed: -5
Broken pipe
qemu-system-i386: load of migration failed: Invalid argument
/home/peter.maydell/qemu/tests/libqtest.c:135: kill_qemu() tried to
terminate QEMU process but encountered exit status 1
Aborted
ERROR - too few tests run (expected 8, got 7)

I did a retry by hand of 'make check-qtest-i386' and this time
it hung entirely when trying to run that test case.

I also tried a run under valgrind on x86 (you'll need to
nobble KVM somehow as valgrind can't deal with it):
QTEST_QEMU_BINARY='valgrind --smc-check=all
i386-softmmu/qemu-system-i386' QTEST_QEMU_IMG=qemu-img
tests/migration-test -m=quick -p '/i386/migration/multifd/tcp'

and that seems to have hung too.

thanks
