A crash like this normally means running out of address space. I'm not sure if this swapped_out_or_unallocated value is a smoking gun or not.

ReadOnly portion of Libraries: Total=157.5M resident=174.0M(111%) swapped_out_or_unallocated=16777216.0T(11172135829504%)
Writable regions: Total=78.0M written=3216K(4%) resident=4580K(6%) swapped_out=0K(0%) unallocated=73.5M(94%)

I think Gavin broke 32-bit Intel in r100037 as DemandExecutableAllocator is not compatible with MAP_JIT.

The obvious workaround for the meantime is to run Safari as 64-bit. There’s no good reason to run Safari as 32-bit on Lion.

Ooops, resolved in r100175.

Going to 64 bit solved the situation, however, some of the sites I go to regular require 32 bit due to old videos that cannot view with 64 bit Safari/Webkit. Thanks for the help!!!
