I don't know anything about your problem area, but some tools in our
test suite that might help you get better results with an intermittent
problem (if you didn't already know about them):
- add:
GIT_TEST_OPTS = -x --verbose-log
into config.mak. Then when a "make test" run fails, you can see the
log in t/test-results/t7527-*.out.
- try running:
./t7527-* --stress
which will run a bunch of instances simultaneously, with the idea
that the load will introduce timing issues that will trigger the
bug. The failed instance will produce a detailed log on stdout.
That might help you get more output from the failing cases.
