>Description:
PHP 4 and 5 build with system gcc (gcc version 3.4.4 [FreeBSD] 20050518) or 3.4 from ports (gcc version 3.4.6 20060221 (prerelease) [FreeBSD]) returns wrong value
% php -r 'var_dump(-4653896912^1);'
int(-2147483647)
The same php source build with gcc295 or gcc32 from ports returns correct value:
% php -r 'var_dump(-4653896912^1);'
int(-358929615)
Problem doesn't exist on 5.x gcc 3.4.2
