Re: Testing times
Surely you would hire a PHP developer if you need some PHP written? And of course, you are smart enough to recognise the difference between the language PHP and C that it's engine and other gubbinz are written in, aren't you? Although that would mean you wouldn't recruit any C developers as surely they are tainted by association. And as C developers rule the world (sorry Java/Perl :-) ) that kinda narrows down the talent pool.
On a side note i suspect this bug hasn't been noticed because anyone using PHP for serious maths heavy work uses a combination of 64bit (where the bug doesn't seem to exist), and BC math or GNU Multiple Precision extensions which i suspect don't touch the bug causing code
(I suspect i may have just fed the troll but oh well)
