Verified that this is another SIGBUS (OOM) (same as  bug 633475  and  bug 598724  and others), but the report says SEGV.

Received signal 7 BUS_ADRERR 7f90181a3ff0

kcc, if we can't change the report output to give us a way to distinguish between SIGBUS and SIGSEGV, would something behind an ASAN_OPTIONS flag be possible?
