PHP: 2 tests failing on armv7h

[TPXP]

Hi !

I tried rebuilding the PHP package on my armv7h board (an Odroid-XU), with an additional patch to avoid a critical bug with older kernels : see viewtopic.php?f=15&t=11321&p=54787&hilit=could+gather+random#p54787 , patch here : https://github.com/php/php-src/pull/2385 .

It built correctly, but failed while check()ing:

The failing tests can be found here :

https://github.com/php/php-src/blob/mas ... 32bit.phpt

When trying to run them on the package provided by the ALARM repository, I got these results :
$this->bbcode_second_pass_code('', '$ php dval_to_lval_32.phpt
--TEST--

')
The test runs fine on my Archlinux x86_64 computer, so this is a bug in the ARM version. Perhaps it is due to the way the ARM architecture deals with integer conversions ? Maybe a compiler flag can fix this ?

Thanks in advance for your help.
