I cannot reproduce this with WebKit ToT build on Mac. Also, there have been some fixes for Qt in this area (like bug 67562), so maybe this is already fixed?
(In reply to comment #2) > I cannot reproduce this with WebKit ToT build on Mac. Also, there have been some fixes for Qt in this area (like bug 67562), so maybe this is already fixed? I believe this is due to the fact that prior to r94514 on Qt, WTF::double_conversion::initialize() is never called, thus kCachedPowers is still null when it is derefed, causing a segfault. As Alexey suggested, this issue should be fixed in bug 67562. *** This bug has been marked as a duplicate of bug 67652 ***

The OS I used is ubuntu-11.04-desktop-i386; The Qt libraries I used are fetech via apt-get install libqt4-dev libqt4-gui The source package I used is WebKit-r94508.tar.bz2 Best regards
