[PHP-DEV] [PHP5.0.3RC1] C Extension Function not Found Anymore

[Bruce Bailey]

I have an extension written in C running with PHP4.3.9 on RH8.  All 
functions performed as expected.  When I upgraded to PHP5.0.3RC1, for some 
reason when I try to call a particular function, httpd (or php) dumps core.  
It seems to be only one function.  The rest appear to work as I expect them 
to.  I added some file tracing at the very beginning of the function, (just 
after the local variable declarations and before the call to 
zend_parse_parameters).  The trace is never being executed.

As far as I can tell, my function is never being called – it appears that 
the interpreter is dying.  I don't see any errors in the PHP error log, as I 
might expect if the function name were mistyped or something like that.

Have there been changes in the way that functions are looked up or called?
How many characters of the function name are used to discriminate between 
functions?
Is there a way I can examine the function name/function pointer cross 
reference table?

Thanks in advance,
Bruce
