function xsl_error($parser, $code, $level, $errors)
{
  ...
  die("this will cause a coredump or fatal trap");
}

xslt_set_error_handler($parser, "xsl_error");

by calling die() inside a function for xslt_set_error_handler will cause my NetBSD/Alpha system to either coredump or go to a fatal user trap. it coredumps if i didn't compile with '--enable-debug'. with debug compiled in, it usually reports a fatal user trap. this only happens with the PHP Apache DSO. as a cgi, it exits just fine.

i've verified and repeated this on PHP 4.0.5 and the latest cvs.

please try the new XSLT extension (use the CVS version, 
--enable-xslt --with-xslt-sablot) and let me know if this 
still happens.
