Previous Comments: ------------------------------------------------------------------------ [2014-09-19 18:20:54] vostreltsov at gmail dot com Description: ------------ So in my project I have an auto-generated lexer, it contains a big array. I created a simplified script that reproduces the bug. There are 65538 integers and it looks like something overflows inside PHP. The var_dump call ouputs an array of only the last 2 numbers. Removing last 2 numbers yields an empty array. If I remove last 3 numbers, the output stops at key 32766, that is 32767 values. Test script: --------------- http://filebin.ca/1atoDItGZU2A Expected result: ---------------- All of 65538 integers Actual result: -------------- array(2) { [0]=> int(0) [1]=> int(0) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68057&edit=1
