And here's a back-trace from ompi_info:
==========================================
Program received signal SIGSEGV, Segmentation fault.

=============================================
HOWEVER: If I configure with --enable-debug, two things happen:
1. I have to build ompi/mca/rcache/rb by hand because of incorrect
CFLAGS;
2. The SegFault disappears.
(The line# in #0 above is incorrect; by accident I edited the email as I
was writing it and erased too much. I can rebuild with '-g' but not
with --enable-debug if necessary.)
