PHP Bug Type: Reproducible crash
Bug description: xlst_error causes error with valid XSLT processor instance
the following code causes Apache processes to segfault:
$xsl_handle = xslt_create();
echo $xsl_handle; // returns a valid xslt processor handle
// $xslData and $xmlData contain valid information
xslt_process($xslData, $xmlData, $result);
echo xslt_error($xsl_handle);
xslt_free($xsl_handle);
This piece of code also returns a "Warning: Supplied argument is not a
valid XSLT Processor resource in *** on line 27", where line 27 is
"xslt_process($xslData, $xmlData, $result);
"
Backtrace:
Program received signal SIGSEGV, Segmentation fault.
