In function static float php_ifd_get_float(char *data) of php-src/ext/exif/exif.c ,the 3rd byte (data[2]) is referring to -8(Hex: fffffff8 ),where as its referred to 248 (Hex: f8) on s390x as char is treated as unsigned char. could you please guide us on what could possibly help to tackle the above scenario? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79430&edit=1
