--- Comment #20 from Julian Seward <jsew...@acm.org> ---
Looking at the end of the log there:

SYSCALL[279836,1](291) sys_newfstatat ( 24, 0x4a73980(), 0x4ad2578 )[sync] -->
Failure(0x9) 
SYSCALL[279836,1](90) sys_mmap ( 0x0, 0, 1, 2, 24, 0 ) --> [pre-fail]
Failure(0x16) 
==279836== 
==279836== Process terminating with default action of signal 11 (SIGSEGV):
dumping core

The mmap call is marked "[pre-fail]", which means that V never passed it
to the kernel.  Instead it decided to "fail" it itself, for the reason 0x16,
whatever that is.  Might be worth investigating.

Also I wonder if the failure of the immediately preceding sys_newfstatat
syscall is related.
