Description: ------------ I run php-trunk-201008060430's "make test" under a tool that detects integer undefined behaviors. This is on an x86 box running Ubuntu 10.04. The list of problems is below. Some of these could be security problems waiting to happen. Hopefully the error messages are self-explanatory. If more details are required, please let me know. </home/regehr/z/php-trunk-201008060430/Zend/zend_compile.c, (5144:5)> : Op: +, Reason : Signed Addition Overflow, BINARY OPERATION: left (int32):
