thanks.  I see that the fast majority of failures is with

compiler exited with status -1
output is:
spawn failed

I saw them myself at a time, and under par found

11260mS          expect(517760): open("/dev/ptmx", O_RDWR, 037777777777) = 8
11261mS          expect(517760): stat("/dev/pts/2", 0x7ffae0f0) errno = 2 (No such file or directory)

For some reason, ptys weren't created on demand, but had to be created
manually since /dev/MAKEDEV had no support for that.  I never found out
what was wrong, but the problem hasn't bitten me since.

Exactly.  At least on Tru64 UNIX, newer versions even fail their own
tests, and we had similar reports e.g. on SPARC.

Those should be fine.
