http://trac.webkit.org/changeset/158214 made almost all tests crash on GTK and EFL
See the EFL bot for detailed crash logs:
Unfortunately the GTK release bot doesn't provide crash logs and tests pass on the GTK debug bot.
Shouldn't we disable simple line layout again on !MAC platforms until proper fix?
The Layout struct should use the WTF_MAKE_FAST_ALLOCATED macro. TcMalloc (which is enabled on release configurations of the affected ports) was used to allocate the memory, so it should also handle its deallocation.
Bug #120246 covered a very similar regression.
