Description: ------------ COPY FROM : https://bugs.php.net/bug.php?id=45392 STILL NOT FIXED, BUT BUG IS CLOSED !! When memory_limit is reached, and one is using the output buffering functions, instead of just dying with an "out of memory" error, the contents of the buffer are spilled onto stdout. The output_buffering ini setting wasn't set to any particular limit. Test script: --------------- <?php ob_start(); $i = 0; while($i++ < 10000000) { echo str_repeat("lol", 42); } ob_end_clean(); /*Note that the 10,000,000 number varies according to your memory_limit*/ Expected result: ---------------- STDERR: Fatal error: Allowed memory size of 134217728 bytes exhausted at /home/flebron/cvs/php/php5.3-200806291230/main/output.c:395 (tried to allocate 133693441 bytes) in /home/flebron/cvs/php/ob.php on line 5 Actual result: -------------- STDERR: Fatal error: Allowed memory size of 134217728 bytes exhausted at /home/flebron/cvs/php/php5.3-200806291230/main/output.c:395 (tried to allocate 133693441 bytes) in /home/flebron/cvs/php/ob.php on line 5 STDOUT: The text in the buffer is printed to stdout (millions of "lolol"s).
