Bug #64888 [NEW]: Integer Overflow when processing MAX_FILE_SIZE

From: php at paalsteek dot de Operating system: Arch Linux PHP version: 5.4.15 Package: FPM related Bug Type: Bug Bug description:Integer Overflow when processing MAX_FILE_SIZE Description: ------------ When uploading files I get an error UPLOAD_ERR_FORM_SIZE when setting MAX_FILE_SIZE in the input form to values greater or equal to 2147483648 (2^31). This problem does not exist on a CentOS 6.4 using Apache 2.2.15. Therefore I guess this is an implementation specific problem of php-fpm.
