Re: Java call on object causes segfault.

Whenever you get a segfault, try the latest stable release and during compile be sure to use --enable-debug : http://snaps.php.net/ If the segfault exists here, write a bug report and include the backtrace: http://bugs.php.net/how-to-report.php http://bugs.php.net/ This will be of great help to the php-dev team. Also I believe many changes to the Java extension went into 4.3.0 so maybe it'll work for you. Regards, Philip On Sun, 26 Jan 2003, John Wells wrote: > Working on getting Java integration going.
