(several lines about vg_replace_malloc.c skipped) master.err: main.events_grant: ==26115== at 0x4A20A56: malloc (vg_replace_malloc.c:149) master.err: main.events_grant: Attempting backtrace. You can use the following information to find out master.err: main.events_grant: mysqld: table.cc:342: void free_table_share(TABLE_SHARE*): Assertion `share->ref_count == 0' failed. There are also four server logs like quoted in the initial bug report.

Can't repeat. Tested on my local machine under valgrind and on the PB valgrind host with the binaries that failed the test. I run test several times, the bug doesn't appear.
