--- Comment #9 from Chris Jefferson <chris at bubblescope dot net> 2012-04-23 10:54:57 UTC --- Looking at the output of -fdump-tree-all, it looks like the compiler optimises the loop which accesses an array out of bounds to: while(true); Is this expected behaviour? That seems like terrible output for every situation...
