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. Ken
