Bug description:Memory leak with phpinfo() + output buffering + zlib compression
Description:
------------
There is a memory leak on memory allocated on \main\output.c(809):
if ((handler->buffer.size - handler->buffer.used) <= buf->used)
{
size_t grow_int =
PHP_OUTPUT_HANDLER_INITBUF_SIZE(handler->size);
size_t grow_buf =
PHP_OUTPUT_HANDLER_INITBUF_SIZE(buf->used -
(handler->buffer.size - handler->buffer.used));
size_t grow_max = MAX(grow_int, grow_buf);
handler->buffer.data = erealloc(handler->buffer.data,
handler->buffer.size + grow_max); /* memory was allocated here */
handler->buffer.size += grow_max;
}
phpinfo() code:
/* Andale! Andale! Yee-Hah! */
php_output_start_default(TSRMLS_C);
php_print_info(flag TSRMLS_CC);
php_output_end(TSRMLS_C);
Test script:
---------------
File file.php
---
<?php
phpinfo();
(only the non disablable modules are loaded)
php-cgi -dzlib.output_compression=1 -doutput_buffering=10K file.php
