Bill Blough commented on XALANC-751:
------------------------------------

Note, the "xalan" executable in the example above is a renamed TestXSLT.  Similar behavior occurs with XalanExe.

>         Environment: Debian GNU/Linux

> TestXSLT segfaults under certain input instead of returning an error.  My testing indicates that this issue began in SVN rev 1388736, as 1388735 appears to exhibit the correct behavior.
> The issue can be reproduced as follows:
> $ cat var-in-xslkey.xsl
> <?xml version="1.0"?>
> <xsl:stylesheet version="1.0"
>                 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
> <xsl:param name="var"/>
> <xsl:key name="key" match="*[@id != $var]" use="''"/>
> </xsl:stylesheet>
> $ xalan -xsl var-in-xslkey.xsl -in var-in-xslkey.xsl
> Expected Results (1388735 and before):
> XSLException Type is: XPathParserException
> Message is: A variable reference is allowed in a match pattern or
> expression in this context.
> pattern = '*[@id != $var]' Remaining tokens are:  ( 'var' ']')
> (var-in-xslkey.xsl, line 5, column 54)
> Actual Results (1388736 and later):
> XPath error: A variable reference is allowed in a match pattern or expression in this context.
> pattern = '*[@id != $var]' Remaining tokens are:  ( 'var' ']') (Occurred in an unknown entity, at line 5, column 5.)
> Segmentation fault
