Comment 1 Dario Andres 2009-07-10 17:05:28 UTC
This reminds me bug 186621. But it seems it is not the same
Thanks
Comment 2 Joris Guisson 2009-07-10 18:37:31 UTC
It's the same problem, in 186621 the backtrace is probably from a debug build and this is from an optimized build (some functions are inlined, so they don't show up in the backtrace)
