Bug description: crc32() function result differs on 64-bit Linux platforms and
others
Description:
------------
According to bug# 36306, this issue should have been fixed. But I found
it not entirely fixed across all platforms.
crc32 is returning an unsigned integer on a 64-bit Linux platform. It
does return the signed integer from a 64-bit Windows platform as well as
32-bit Windows/Linux platforms.
I found PHP_INT_SIZE and PHP_INT_MAX constants have different values on
that 64-bit Linux server with values 8 and 9223372036854775807
respectively. They are 4 and 2147483647 on other 32-bit platforms and
64-bit Windows platform.
Reproduce code:
---------------
<? echo crc32("884385799717_1_1") . "\n"; ?>
Expected result:
----------------
I expect to see value -676770709 both on 32-bit and 64-bit platforms.
Actual result:
--------------
On 64-bit Linux platform I see 3618196587
On 64-bit Windows platform I see -676770709
On 32-bit platforms I see -676770709
