--- Comment #3 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
I have attached backtraces of the crash (both in Debug and Release mode).

When running in Debug mode it takes a bit longer to crash than on Release (somehow expected). But it seems it crashes on a different part.


On Debug https://bugs.webkit.org/attachment.cgi?id=317188 :

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007f88b1628fb1 in bmalloc::FixedVector<bmalloc::BumpRange, 3ul>::pop() (this=0x7f88bdca20f0) at /home/clopez/webkit/webkit/Source/bmalloc/bmalloc/FixedVector.h:101
101         return m_buffer[--m_size];

On Release https://bugs.webkit.org/attachment.cgi?id=317189 :

Program terminated with signal SIGSEGV, Segmentation fault.
