2.37, right? :)

There are a few options:

1) Apply the patch in the normal way and rebuild the world. If the
changes in the patch are limited to fixing this bug, then we can be
confident that changing binutils will not break other packages, which is
the main goal behind "freezing" the core-updates branch. Do you think
that expectation is reasonable? Otherwise, the branch is frozen except
for bug fixes; we'd like to avoid rebuilding the world but it's not a
problem if we have to.
2) Create a binutils-fixed package and only use it for qtwebkit and
3) Try to work around the bug in the qtwebkit and qtwebengine packages

2 and 3 are not great because maybe the bug affects other packages in
some situations. Do you know if it manifests deterministically?
