Bug description: pdo_pgsql: segfault with multiple rows and prepared statements
Description:
------------
Hi,
i can't provide reproduce code. All i can say is that i use prepared
statements with multiple rows (INSERT .. VALUES (..), (...)) and on a table
with huge data php segfaults.
If executed with 100 rows per Statement PHP fails with "zend_mm_heap
corrupted", this core was created with 20 rows. The rows contain binary
data and are all about 1-3mb.
Here is the backtrace, i hope it helps:
Core was generated by `php -q index.php'.
Program terminated with signal 11, Segmentation fault.
