See <URL:http://bugzilla.redhat.com/bugzilla> for instructions. Similar problems occur with qt-everywhere-opensource-src-4.7.4.tar.gz. This started happening after the most recent compiler update.
Please attach preprocessed testcase on which it can be reproduced. You need to disable PCH (try removing that -include .pch/release-shared/QtCore and see whether it still segfaults), add -save-temps and attach qfactoryloader.ii it creates.
Excuse me for being a bit blunt, but are you asking because you couldn't reproduce the problem with the suggested build, but if you didn't bother to try?
That should be "*because* you didn't bother to try", of course... I mean, I don't think it's too much to ask for a package maintainer to try the original steps for reproduction before asking for info here, even though the problem is not quite as isolated as one might want in an ideal world.
I'm asking that from all bugreporters, see e.g. http://gcc.gnu.org/bugs.html for more detailed bugreporting instructions. Generating preprocessed source is quite easy when you have the setup where you can reproduce the problem, and ensures that it is easily reproduceable everywhere. The compiler crash may and often does on many other packages you've installed (headers), and to reproduce one would need to match your exact environment (which you haven't even specified in detail).
Well, I suspected as much, but I don't agree with that policy. The fist response to a bug report should never be an "automatic" answer IMO, you should always try to reproduce based on the information already provided first. But I'm not the one who actuall entered this report...

This also happens in 32 bit i386 version. Note that the .pch/debug-shared/ directory is empty.
