[Qemu-devel] Core dumps - commit a0abe474d587499a1553372c1692811f81fd3eda

[Gerhard Wiesinger]

Hi,

I'm getting coredumps:
#0  qemu_opt_find (opts=0x0, name=0x7f18e8c833db "kernel") at qemu-option.c:535
535         QTAILQ_FOREACH_REVERSE(opt, &opts->head, QemuOptHead, next) {

I bisected it down to the following commit:
a0abe474d587499a1553372c1692811f81fd3eda is the first bad commit
commit a0abe474d587499a1553372c1692811f81fd3eda
Author: Peter Maydell <peter.maydell@linaro.org>
Date:   Wed Feb 8 05:41:39 2012 +0000

     Make kernel, initrd and append be machine_opts

     Make kernel, initrd, append be machine opts (ie -machine kernel=foo)
     with the old plain command line arguments as legacy/convenience
     equivalents.
