Re comment #1: it's a generic bug in reorg.c (fill_slots_from_thread).
I'm testing a patch.

This works in 3.4.0 and 4.0.0 so this is either a regression or a bug in
redhat's compiler or a bug in the patch.

Confirmed, 3.2.3 did not ICE, though it did just ignore may_alias after warning
about it. I am going to mark this a regression as the ICE is a regression for
the code.

This happens with Qt4 Win32 as well - lot of warnings - warning: inline

type of flag to mingw to suppress these warnings.
