Summary0001176: SIGSEGV, Segmentation fault
DescriptionI am inserting multiple rows in one PDO statement to MySQL. When one of those rows triggers a database error (duplicate key for example) php5-fpm throws a SIGSEGV when the total rows is larger than a certain size.

Looking at the core dump (attached) it seems xdebug is the cause. With xdebug disabled there is no issue.

PHP Version:
XDebug Version: 2.3.2
pdo_mysql client API version => mysqlnd 5.0.11-dev - 20120503
Steps To Reproduce- Execute a multi insert statement "INSERT INTO x VALUES (), (), ()" where at least one row will trigger a duplicate key, and with a large number of total rows
- A PDOException is thrown (in my case I am using illuminate/database and a Illuminate\\Database\\QueryException is thrown as seen in the trace) however php5-fpm seg faults.
- Decreasing the number of total rows in the insert sometimes resolves the issue.
