Zeev, I have done some more testing and came to the conclusion that the problem has to be in zend. Any zend_function_entry containing more than 5 methods of a class make php4 die if any of the methods is called. This happens in the domxml extension but also with the directory functions if you put some dummy functions into the class to exceed the magic number of 5. Here ist a small example to reproduce it. Take the following small script and execute it: <?php $d = dir("/"); while($dir= $d->read()) echo $dir."\n"; ?> It should work without any problems. Now, add 3 more functions to php_dir_class_functions[] in ext/standart/dir.c static zend_function_entry php_dir_class_functions[] = { PHP_FALIAS(close, closedir, NULL) PHP_FALIAS(rewind, rewinddir, NULL) PHP_FALIAS(read, readdir, NULL) PHP_FALIAS(xread, readdir, NULL) PHP_FALIAS(yread, readdir, NULL) PHP_FALIAS(zread, readdir, NULL) {NULL, NULL, NULL} }; Recompile php4 and run the script again. Now I get Fatal System Error: Raise at top of Exception Stack Abort If you take out any of the functions it works again. If you change the script to <?php $d = opendir("/"); while($dir= readdir($d)) echo $dir."\n"; ?> it also works. Maybe the problem is in INIT_CLASS_ENTRY()? Could you or somebody with more knowledge of zend have a look at it, since I'd like to keep working on the domxml extension. Thanks.
