Working with number larger than 65,535 is failing with a floating point exception with hphp. This simple program compiles fine but does not run: <?php $i = 65536; $i++; echo $i; Compiling with hiphop-php/src/hphp/hphp includeperf.php gives the error: Floating point exception This kind of error usually only occurs when trying to do illegal operations such as dividing by zero but this operation should be simple integer arithmetic and not any floating point operations. I'll see if I can track down the cause of the problem but I wanted to see if it was a known issue first. It seems to prevent larger code bases such as Wordpress from running as well.
