FWIW, and this applies to bugs 18367, 18368 and 18369, too, the crash happens
when building with -O1, with -O2, but NOT when building with -O0 or -fdefer-pop
-fdelayed-branch -fguess-branch-probability -fcprop-registers -fif-conversion
-fif-conversion2 -ftree-ccp -ftree-dce -ftree-dominator-opts -ftree-dse
-ftree-ter -ftree-lrs -ftree-sra -ftree-copyrename -ftree-fre -ftree-ch
-funit-at-a-time -fmerge-constants, which is listed in gcc's man as being the
flags -O1 turn on.

Note that a -O1 build is significantly faster on the tests that pass than a
build with all these flags, so obviously, gcc does much more than what it
claims.
