Replying to my own message.
I lied.
After re-testing the "-D 2011-05-03" version, I DID get it to fail.
The test case I've been using runs 20 iterations of about 45
seconds each.
Normally, one run is enough, but sometimes it seems to run several
iterations
clean, and then fail. I **think* that something about the load on the
machine helps trigger the error. I have tried to isolate this, but
the
pattern is not clear.
In any case, I ran the test 3 more times on the 2011-05-03 build,
and it
failed 2 of the 3 runs.
-D 2011-05-01 looks clean
-D 2011-05-03 looks bad.
Looks to me like matt broke something. ;->
I kept the several of the relevant build directories, so I am in a
good
position to test fixes if they should appear. I don't have a build
dir
for HEAD, but could set one up. My test scripts require some
relatively large data files, so they are not so easy to "deliver" to
someone else.
