Re: Overloading methods : segfaults

Yep and you might also want to look at the PECL Perl extension. Both are good resources. Andi At 03:15 PM 9/27/2004 +0100, Wez Furlong wrote:

Take a look at the com_handlers.c file in the com_dotnet extension to see how to handle this kind of thing. --Wez.

I am writing a PHP extension implementing an embedded Ruby interpreter (http://www.ruby-lang.org/). It requires method and property overloading. Overloading was successfully implemented in ZE1 version of extension. When porting the extension to ZE2, I have faced with segfaults when calling overloaded methods (no problem with property overloading). I suspected that the problem may be caused by external libraries, and wrote a minimalistic test extension (see attachment). It simply prints out name of called method, but the problem is the same.
