PHP Bug Type: Scripting Engine problem
Bug description: debug_print_backtrace() leaks
<?php
function foo()
{
debug_print_backtrace();
}
foo();
?>
After running the above script, the memory manager reports following
leaks:
/home/koizumi/src/php.net/HEAD/php4/Zend/zend_hash.c(178) : Freeing
0x0827FD54
(32 bytes), script=/tmp/test3.php
