Well, it is part of the new 5.4 signal handling code that defers these signals, including SIGUSR2, when inside a critical section. In order to determine where it is used you have to look at the environment PHP is running in. You can't figure this out just by looking at the PHP code. Not deferring SIGUSR2 just because valgrind on OSX doesn't like it isn't really an option here. We could make debug builds on OSX not defer it, I suppose. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
