Bug description: 0+0=4G on aix4.3 (64bits)
Script:
<?
echo '0+0=', 0+0, "\n";
?>
Output of script on php 4.2.3:
0+0=4294967294
which is equal to 2^32-2
(Output of script on php 4.1.2 and 4.0.6:
0+0=4294967296
which is equal to 2^32).
In general, all simple additions and multiplications produce huge
numbers:
0+0=4294967294
0+1=4294967295
1+0=4294967295
1+1=4294967296
0-0=0
0-1=-1
1-0=1
1-1=0
0*0=3.5178585246345E+18
0*1=3.5178585265101E+18
1*0=3.5178585265101E+18
1*1=3.5178585283857E+18
0/1=0
1/1=1
2/1=2

I don't know if it is very relevant but the rs6000 on which aix4.3 is
running
is a 64bits machine. The c program
int main()
{
printf("long=%dbits\n",8*sizeof(long));
return 0;
}
outputs 'long=64bits' when compiled with 'cc -q64', while when compiled
with 'gcc' it outputs 'long=32bits'.
Thanks very much in advance,
Rein van Vliet
