Bug description: str_replace leaks when replacing text in arrays
Description:
------------
Replacing items in an array of 20-30 items with str_replace seems to leak
memory. The application in question would crash when parsing various larger
CSV files, using upwards to >500MB per an 18MB data-file.
Jumps in memory usage were observed at the point where str_replace was
run. Using the function 'preg_replace' instead issued no such leak
Reproduce code:
---------------
str_replace('~comma~', ',', $myarray );
Expected result:
----------------
(values of ~comma~ in string were replaced with actual commas)
Actual result:
--------------
Progress would end indicating in logs that the memory limit of 500MB (as
indicated in php.ini) was exceeded.
