Re: Regressions in code coverage in sql_join_cache in maria-5.3-mwl128
The reason seems to be that the join_cache test failed in the gcov build:

main.join_cache w1 [ fail ]
Test ended at 2010-10-23 19:22:36

CURRENT_TEST: main.join_cache

Build and compile information are available from http://buildbot.askmonty.org/buildbot/builders/gcov/builds/38 . No idea why.

Igor pushed a --sort-result test case fix and the coverage percentages are back to normal.
