This is primarily a problem with the InnoDB plugin since more work is done in the if (ptr) block, however it does affect earlier version of InnoDB as well. Note that currently, this is only called if you use the --large-pages start-up option. It is a relatively trivial, unrisky fix to do imo.

Jimmy, could you have a look. Mark, we still need to call shmctl() to remove the shared memory segment if shmat() fails. My proposed fiz therefore is to add ptr = NULL; after that shmctl to avoid entering if (ptr) block

Agreed. In case of shmat() failure, shmctl() with IPC_RMID still needs to be called, and 'if (ptr)' block should be skipped and fall through to ut_malloc_low(). Good catch. Thanks Jimmy

Noted in 5.1.41, 5.5.0, 6.0.14 changelogs. Memory-allocation failures were handled incorrectly in the InnoDB os_mem_alloc_large() function.
