Description Duncan 2009-05-23 11:22:06 UTC

This bug is I suppose the "backport version" of bug #267720, where the kdelibs-4.2 version of kjs was crashing when compiled with gcc-4.4.0 without -fno-strict-aliasing.  From the comments on the kde bug therein referenced, it appears the patched code was likely from pre-kde4, so the patch should be pretty similar I'd hope.

A lazy alternative, given the age and status of kde3, may be to simply check the gcc version and appendflags -fno-strict-aliasing if >=4.4.0.  That (well, the /etc/portage/env/kde-base/kdelibs file equivalent) is what I've done as a temporary workaround, and I can get to my bank without my browser crashing again! =:^)

Marking critical due to the crashes, noting also the "interesting" security implications a browser crash may conjure.

It's unlikely that emerge --info will be useful beyond the gcc-4.4.0, but I'll attach it just in case.
