Interestingly adding all of the options enabled at -O1 to -O0...
-O0 -fcombine-stack-adjustments -fcompare-elim -fcprop-registers -fdefer-pop
-fforward-propagate -fguess-branch-probability -fif-conversion -fif-conversion2
-fipa-profile -fipa-pure-const -fipa-reference -fmerge-constants
-fsplit-wide-types -ftree-bit-ccp -ftree-ccp -ftree-ch -ftree-copy-prop
-ftree-copyrename -ftree-dce -ftree-dominator-opts -ftree-dse -ftree-fre
-ftree-sink -ftree-sra -ftree-ter
doesn't trigger the miscompilation.
