Subject: Re: [PHP-DEV] Re: SegFault 11 on 5.5.6 on function return
From: ralph@ralphschindler.com (Ralph Schindler)


> Can you confirm that the bug is *not* in 5.5.5 but 5.5.6 only ?

I wouldn't say I can confirm that conclusively.

With 5.5.5 compiled the exact same way on my mac, I do not get the 
segfault.  Given the class of problem though- I think that me not being 
able to reproduce should be considered anecdotal.

Dmitry was able to locally confirm the issue in PHP-5.5 and said he'd 
look at it tomorrow in more depth.  He used valgrind to identify 
problems in the 5.5 branch.

I think his methods (valgrind, extensive gdb introspection) will produce 
a more reliable idea of what is actually going wrong and when it might 
have been introduced.

Thanks,
