note 75303 modified in oci8.setup by sixd

Regarding issues with glibc "double free or corruption" or "free(): invalid next size" errors in error_log with PHP4 (PHP 4.4.7 is still afftected by this issue), and in addition to Rainer Klier´s notes below, if you´re using autoconf 2.5 (default on Redhat ES/CentOS 4.4 and 5, for example), you must delete PHP´s "configure" script before running "buildconf --force", or it will do nothing. After that, you´ll need to use PHP 5 oci8 syntax with configure: --oci8=instantclient,/path/to/instantclient Only after this you´ll be able to compile PHP, but it´s a guaranteed fix - and, just to enforce Rainer´s point (as opposed to what has been said in other places), no need to rise memory limit and edit Makefile on x86-32. Good luck. ;) --was-- Regarding issues with glibc "double free or corruption" or "free(): invalid next size" errors in error_log with PHP4 (PHP 4.4.7 is still afftected by this issue), and in addition to Rainer Klier´s notes below, if you´re using autoconf 2.5 (default on Redhat ES/CentOS 4.4 and 5, for example), you must delete PHP´s "configure" script before running "buildconf --force", or it will do nothing.
