In running "./Build testcover", I get the following message:
Test Summary Report
Files=51, Tests=10514, 3227 wallclock secs ( 2.15 usr 0.36 sys +
3065.45 cusr 63.34 csys = 3131.30 CPU)
Failed 2/51 test programs. 0/10514 subtests failed.
Note that it did not say which test programs failed, or why.
Needless to say, with this size of test suite, it's difficult to
replicate the problem and the failure disappeared in my scrollback
buffer. I also don't have time (sorry!) to rerun this right now with
just "./Build test". I'll try to get back to this later and see if I
can track this down, but if anyone else has seen this, it would be nice
to know that it's not just something deeply strange in our environment.
