Description David Binderman 2013-03-17 17:57:59 UTC 
I just tried to compile the package qtwebkit-2.3-0.6.rc1.fc19
on gcc-4.9 trunk dated 20130317 on an AMD x86_64 box.

The compiler said

BUILD/webkit-qtwebkit-23/Source/WTF/wtf/PassRefPtr.h:160:47: internal compiler error: Segmentation fault
     template<typename T> inline PassRefPtr<T> adoptRef(T* p)
                                               ^

Running under valgrind gives

==6025==
==6025== Process terminating with default action of signal 11 (SIGSEGV)
==6025==  General Protection Fault
==6025==    at 0x1154DA3: backtrace_dwarf_add (dwarf.c:1438)
==6025==    by 0x114EE70: backtrace_initialize (elf.c:757)
==6025==    by 0x114D5FB: backtrace_pcinfo (fileline.c:144)
==6025==    by 0x114CECF: unwind (backtrace.c:83)

Preprocessed source code attached. No special flags required.
