## #15892 — Derick Rethans — 2005-04-07T13:42:51+00:00

Hello Andi,

the following patch fixes issues when ZEND_ALLOC is set to 0 (to be able 
to debug memory related issues in / with the engine):

http://files.derickrethans.nl/patches/zend-alloc-strndup-20050407.patch

This is because estrdup needs to allocate one more byte than the length 
and you can't do that differently with strdup. I'd like to commit this 
patch to all branches.

regards,
Derick

Nice try ;)
