--- Comment #5 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- Hmm, there is one other source code file within webkit2gtk where -fno-move-loop-invariants does not help. I can only get that particular source file to be compiled if I disable all optimizations. I tried bisecting the flags between -O0 and -O1 but that didn't work as I expected, unfortunately. So, I guess we can't compile webkit2gtk until this bug has been fixed :(.
