--- Begin Message ---Package: php5-cli Version: 5.3.3-7 Severity: normal The included terminal transcript runs a small PHP script which calls strval. The script is run in a loop, at successively higher values of `precision', until a precision is found which causes PHP to crash. Although it's very unlikely to be relevant, I am also including a copy of /proc/cpuinfo on the system on which the terminal transcript was taken. It is a 32-bit machine. *** transcript.strval-bug Script started on Fri 18 Feb 2011 13:30:58 GMT bash$ cat show-bug #!/bin/bash for precision in `seq 500 1073`; do php5 -n -d precision=$precision -r
