Wine 3.0-rc3 console output

SlingPlayer 1.5 crashes when attempting to configure the Slingbox (Alt+E -->
Slingbox Configuration --> Change...) (Slingbox needed)

Native qcap causes a new problem so can't try that as a workaround.

Native quartz needed to get this far.

The crash does not occur in Staging 2.21.

I compiled Wine 3.0-rc3 with -O0 and the crash does not occur. Compiling again
with -O1 or -O2 and the problem returns (did not try -O3). I also receive the
following warning during compilation, but further testing suggests it is not
related:

cc1: warning: unrecognized command line option ‘-Wno-packed-not-aligned’

I tried reverting 6864803f1ab70f9f9e90903b13e67da40973d12a but it did no make
any difference.

I also tried compiling with the following, which the man page claims GCC sets
with -O1, but the crash still didn't occur:
-fomit-frame-pointer -ftree-phiprop -ftree-sink -ftree-slsr -ftree-sra
-ftree-pta -ftree-ter -funit-at-a-time -ftree-copy-prop -ftree-copyrename
-ftree-dce -ftree-dominator-opts -ftree-dse -ftree-forwprop -ftree-fre
-fmove-loop-invariants -fshrink-wrap -fsplit-wide-types -ftree-bit-ccp

-fif-conversion2 -fif-conversion -fauto-inc-dec -fbranch-count-reg

The crash goes away when reverting commit
01676c5dd6f9fb61b9c4e52595f6e75e21050009 and recompiling.

01676c5dd6f9fb61b9c4e52595f6e75e21050009 is the first bad commit

Staging 2.21 does have this commit, but the binary packages do, beginning with
release 3.0-rc1.

Workaround unknown.
