Gentoo ~amd64, Qt 5.3 branch and stable branch tested
Description
Qt defaults to building with -no-harfbuzz.
It should default to building -qt-harfbuzz.
The goal of the defaults is to provide a sensible build, a build that crashes under some circumstances (e.g. http://lenta.ru , see QTBUG-36099 and below) is not sensible.
Thus the build system should default to something sensible, such as a bundled version of harfbuzz-ng.
Program segfaults during loading, similar to QTBUG-36099, but setting QT_HARFBUZZ to old no longer has an effect (expected since all three patches have been merged in 5.2).
To reproduce (in a minimal example), extract and compile contents of quick-browser-test.tgz ; for a register trace, run through with catchsegv, comment out the signal line in main and recompile, running with catchsegv)
