The Interbase PHP module will crash on multithreaded operating systems because an abstraction of functions from the PHP3 port may not have been debugged yet.  Please recompile your php_interbase.dll with the following changes to fix this problem:

=========================  interbase.c BEFORE  =======================

PHP_MINIT_FUNCTION(ibase)
{
	IBLS_FETCH();

	ZEND_INIT_MODULE_GLOBALS(ibase, php_ibase_init_globals, NULL);

	REGISTER_INI_ENTRIES();

=========================  interbase.c AFTER  ======================

PHP_MINIT_FUNCTION(ibase)
{
//	IBLS_FETCH();
	zend_ibase_globals *ibase_globals;		//AC: This does not need to call ts_resource() yet.

	ZEND_INIT_MODULE_GLOBALS(ibase, php_ibase_init_globals, NULL);

	//AC: because ZEND_INIT_MODULE_GLOBALS creates a new ibase_globals_id, we
	// have to make sure that all globals are saved under that ibase_globals_id
	ibase_globals = ts_resource(ibase_globals_id);

	REGISTER_INI_ENTRIES();

======================================================

... I'm not sure how to get onto the CVS to send this fix in.  Will someone please send it in on my behalf?  Thank you.

Sincerely,

Albert Chau.
