[Qemu-devel] [PATCH] docker: add sanitizers back to clang build

[John Snow <jsnow@redhat.com>]

Fedora23 is but a distant twinkle.
The sanitizer works again, and even if not,
we have --enable-sanitizers now.

The problem is that I do see some ASAN warnings:

  TEST    check-qtest-aarch64: tests/device-introspect-test

Direct leak of 2272 byte(s) in 48 object(s) allocated from:
    #0 0x55aea5598b4e in calloc (/tmp/qemu-test/build/aarch64-softmmu/qemu-system-aarch64+0x19a9b4e)
    #1 0x7f783ff11ce0 in g_malloc0 (/lib64/libglib-2.0.so.0+0x55ce0)

Direct leak of 864 byte(s) in 18 object(s) allocated from:
    #0 0x55aea5598b4e in calloc (/tmp/qemu-test/build/aarch64-softmmu/qemu-system-aarch64+0x19a9b4e)

    #2 0x55aea712b379 in object_initialize_with_type /tmp/qemu-test/src/qom/object.c:467:5


I'd run it again, but it took eight years to get to that point,
it's late and I'm tired.
