I'm observing a qemu crash in qemu-iotests 153 (which does however not seem to make the test case fail). git bisect points me to this patch. I'm getting output like this: *** Error in `/home/kwolf/source/qemu/tests/qemu-iotests/qemu': free(): invalid pointer: 0x0000555f7870f7e0 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x7cbac)[0x7fa9b29a2bac] /lib64/libc.so.6(+0x87a59)[0x7fa9b29ada59] /lib64/libc.so.6(cfree+0x16e)[0x7fa9b29b33be] /lib64/libglib-2.0.so.0(g_free+0xe)[0x7fa9ce462b4e] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x6eb9dc)[0x555f76f489dc] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x30ae4b)[0x555f76b67e4b] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x311558)[0x555f76b6e558] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x6e2d4e)[0x555f76f3fd4e] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x6e5fa0)[0x555f76f42fa0] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x6e2c2e)[0x555f76f3fc2e] /lib64/libglib-2.0.so.0(g_main_context_dispatch+0x157)[0x7fa9ce45d257] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x6e526e)[0x555f76f4226e] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x42349e)[0x555f76c8049e] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x2c27ef)[0x555f76b1f7ef] /lib64/libc.so.6(__libc_start_main+0xea)[0x7fa9b294688a] /home/kwolf/source/qemu/tests/qemu-iotests/qemu(+0x2c5b8a)[0x555f76b22b8a] Interestingly, this doesn't want to produce a core dump for me, so no backtrace with usable function names here. But I assume that you can easily reproduce this yourself. Kevin
