I've just reproduced this issue on latest version (7.1.9) which was compiled from sources for
armv7 platform.

Thanks.
Since this bug can lead to data corruption is it possible to release a new version of PHP with this
fix included in a short time?

I've just tested this and here is what I've found out:
- I can reproduce this when running 32-bit PHP on 64-bit Windows, it does not happen in 64-bit
builds
- The returned value seems to be random, depending on executed code or MySQL statements
- I can reproduce this behavior on PHP 7.1.7 and 7.2.0beta1
Results I got: 0x1508618400000000 0x100000000 0x10c6632400000000 (though this most likely
doesn't mean anything)
