I'm speaking of a NULL dereference on the branch of COND_EXPR which will not get executed. The point of this PR (as far as I understand it) is that an instruction of a branch which should not be evaluated (and thus potentially dangerous) is hoisted into the delay slot of the condition. Fixing the frontend so to not emit the unaligned load (which should not get executed anyway) is just papering over the bug in reorg which causes it to be (partially) executed. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23585
