Hello,
I just installed ArchLinux on a brand new Intel i7 4770S (Haswell) because my old laptop was unable to handle HD content properly under Kdenlive. I have the exact package versions on both machines but when disabling a simple effect in Kdenlive I get a seg fault.
You can see my bug report on Kdenlive bug tracker here: http://www.kdenlive.org/mantis/view.php?id=3186
I then looked at the trace and found this stuff about lock elision that seems very (hardware) specific to Haswell CPU.

I looked at the PKGBUILD for the current glibc 2.18-9 and it has the "--enable-lock-elision" so I used ABS to recompile it without support for it to see if it would make my Kdenlive work again. And yes problem is gone.
Is this a problem with Kdenlive code or lock elision implementation in current glibc? Don't know if this is related but I also had some issues with Digikam when using the default glibc.
Thanks
Alphazo
