Panic running on simh

[Greg Stark <stark%mit.edu@localhost>]

I'm consistently (well twice so far) getting this panic running NetBSD
6.1.5 on a simh VAX 3900.

panic: usrptmap space leakage
cpu0: Begin traceback...
panic: usrptmap space leakage
Stack traceback :
         Process is executing in user space.
cpu0: End traceback...

It does look like others have run into the same problem. It kind of
looks like there's a missing overflow check in one of the shared
memory apis (Postgres uses both sysv and posix mmap depending on what
it detects working)
