I can confirmed this bug. From the first named function in the backtrace, it looks like webkit uses Trampolines which would trigger a pax violation. #1 0x00000306e6a3d769 in ctiTrampoline () from /usr/lib64/libwebkit-1.0.so.2 This may be a hard one to get upstream to fix. A workaround is to disable mprotect with paxctl -m.
Could this be related with bug 338213 ?
(In reply to comment #3) > Could this be related with bug 338213 ? > it looks like it is the same stuff.
