Public bug reported:
Reading the changelog of the current gcc-4.7 package, it does not appear
obvious that a fix for
<URL:http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53239> is in the
current Ubuntu package. This bug causes potential compiler problems in
all languages, but with a focus on typical C++ usage patterns. It was
one of the items getting a last-minute fix in the one-week delay of the
last Fedora release.
I have only read the ChangeLog but don't have Quantal installed, so I
can't say whether this bug is present or not. The ChangeLog does not
list it as fixed compared to the origin 4.7.0 release, but it may just
be inaccurate.
Someone (TM) should take the attachment from comment #6 of the upstream
bug report and test whether the output with -O2 is correct. If it
isn't, it would make sense getting the fix into the Ubuntu-specific
patch of gcc-4.7.0. The bug will not be present in gcc-4.7.1 once that
is released.
