--- Comment #10 from dougkwan at google dot com 2009-10-20 06:22 --- (In reply to comment #9) (In reply to comment #8) This is fixed in trunk but at least gcc-4.4.0, where this bug was found, is still broken. I have no approval rights but can you test ask to backport this to 4.4 branch after the freeze for the 4.4.2 release is lifted ? Sorry about the late reply. Yes, I can prepare a fix for 4.4.2 -Doug -- dougkwan at google dot com changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |dougkwan at google dot com |dot org | Status|NEW |ASSIGNED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41574
