Comment 2 for bug 1438516

Analysis is:
1. The `handler::ha_delete_row' method calls virtual method 'delete_row' that is being overloaded by the storage class implementation such as e.g. `ha_myisam'
2. The traces without resolved name is therefore most likely an implementation methods contained in a shared object without debuginfo.

Questions:
* Is `mysql' starting after that? Is there any binary file corruption?
* What about disk space left?
* Where can I get the exact `mysqld' package content, preferable with debuginfo?
* Please show me the `/proc/<mysql-server pid>/maps' file content.
