core file

[Stewart Smith (stewart)]

this looks like something that is release blocker.

I shall take a close look at all percona-projects-qa bugs soon.

[Oleg Tsarev (tsarev)]

You can merge this bug with #785598 (similar trouble)

[Valentine Gostev (longbow)]

Oleg, there is no need to merge bugs I think. If source of the problem is similar, please link branch with fix to several bugs.

[Oleg Tsarev (tsarev)]

I didn't reproduce on branch
Please reopen with complete information if bug is actual.
