On a remote machine currently with RELENG-6 from 20th. June, with STABLE
sources from this morning I get build failures in contrib/ similar to:

/usr/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc/lcm.c:801: internal
compiler error: Segmentation fault: 11

Would this indicate a hardware (memory) problem?
Yes. The compiler dying with signal 11 is a typical memory problem.
Any way to test remotely?
There are memory test applications like memtest86+ (http://www.memtest.org/).
You have to boot from it, but it does support a console on a serial port.
There is also ports/sysutils/memtest that may be run from multiuser
if one manages to build it with broken memory :-)
Or it's possible to install a package.
One problem with running such application with OS loaded is that
kernel places strict limit to amount of memory that user-level application
may lock. There is a PR with a patch that allows to raise the limit
so memtest could test most part of free memory:
http://www.FreeBSD.org/cgi/query-pr.cgi?pr=kern/114654
Thanks for the memtest advice, I ran it and memory is definitely hosed.
Sigh, that means 400 kilometers of travel...
