Overriding System Class-Method - Segmentation Fault (11) #76

Closed jaydipdave closed 9 years ago

jaydipdave commented 9 years ago

Modified runkit_methods.c and removed all the restrictions to override system class and system functions. Compiled it working fine.

It also works fine, mostly. But sometimes, when frequently called, it give segmentation fault error.

My code below, I am using it with Cakephp framework.

runkit_method_copy('PDO','pprepare', 'PDO', 'prepare');
runkit_method_redefine('PDO','prepare', '$a,$ln=null', 'return PDO::pprepare($a,$ln);');

Any solution?

Thanks, Jaydeep

Overriding system class-methods is prohibited since they are shared between all PHP threads. When you redefine method in one thread other threads' behaviour is unpredictable.
