 Bug Type:         Reproducible crash
 Operating System: Suse Linux 9.0
 PHP Version:      5.2.1
 New Comment:

I found this 'zend_mm_heap corrupted' in my apache log files.

I am using 5.2.5 with almost everything enabled. Mysqli and I am using
Zend Frame work.

As far as I can tell my scripts case this (and a seg fault) when they
are looping through a Zend_DB_Table_Rowset object adding rows to a
table.

When the $row **goes out of scope** the script seg faults. So I get
this error when the function (well method) returns a value. I stripped
all code from the function apart from echos and the $row->save() and the
seg faults still happen.

Ho hum...

john

Hi,

i too got the same issue and this is how the code works,

I am having some scripts to parse the HTML data and wherein i am having
part of the code as ,

				$replaced_key = strtolower(str_replace("%", "percent", $key)); 
				$replaced_key = str_replace(".", "", $replaced_key); 
				$key = str_replace(" ", "_", $replaced_key); 


When i have the above code with the same variable name,

				$key = strtolower(str_ireplace("%", "percent", $key)); 
				$key = str_ireplace(".", "", $key); 
				$key = str_ireplace(" ", "_", $key); 

I get the "zend_mm_heap corrupted" error wherein when changed the code
to the above way, it works fine.
