Comment (by yawning):

 This looks like a GCC bug, someone should check to see if they know about
 it and if not, file one.

 I'm not sure if "add a ton of internal tests to see if the compiler
 generated correct code" makes a whole lot of sense, since as you noted,
 the issue is caught by the test suite.  There's no guarantee that the rest
 of the code is actually being compiled correctly either at this point...

 My initial thoughts on this matter are to add a workaround if GCC ships an
 actual release with this problem.  Otherwise, anyone that braves using a
 development snapshot compiler (or builds tor with non-standard CFLAGS)
 should be running unit tests.

 It's a nickm decision though, so hopefully he sees this soon.
