I could use some help from the MPS experts in debugging the failing
test, which is arenacv. I ran the test under strace and didn't see any
mmap or munmap failures. I'm attaching the test log, which doesn't mean
a thing to me. I also built an unoptimized arenacv and can run it under
gdb if someone tells me what to look for.
TIA.
