http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57970 --- Comment #4 from Chris King --- Sorry, not interested: like I said above, it's very difficult to trigger, and the only code I've been able to trigger it with is proprietary. You can either read sched-deps.c and understand the code path which fails (which I outlined) and how the patch fixes it, or close the bug and ignore the patch. I keep my own branch, so I don't really care.

You can use http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction to reduce the testcase to the smallest one that fails still.
