Description:
Observer during the build of 5.5.0-beta.
It has not been observed before, but that may well be due to the recent change in the test. From the effect I see (and from bug DB entries), this source contains the fix for bug#47808.
I'm not sure whether this is a bug in the server, specific in InnoDB, or in the test.
Symptom:

I have no idea why it was observed only in RPM builds,
I am not aware of any significant difference with the machines or the way tests are run compared to a tar.gz build.
How to repeat:
Found while running the test suite.
