      Description

      Hi,

      I ran into an issue where I am getting a crash during a transform because of a syntax error in the XSL. I am expecting the transformer to report an error instead of a crash. To reproduce the crash:

      1. Edit the SimpleTransform.cpp file located in xalan-c-1.11/c/samples/SimpleTransform to call my crash.xml and crash.xsl files.

      2. Run the transform and see the SIGABRT generated (if compiled in debug mode):
      SimpleTransform: /apps/uadev/tfuas/Dev/build/xalan-c-1.11/c/src/xalanc/XalanDOM/XalanDOMString.cpp:72: xalanc_1_11::XalanDOMString::XalanDOMString(const XalanDOMChar*, xercesc_3_1::MemoryManager&, xalanc_1_11::XalanDOMString::size_type): Assertion `theString != 0' failed.
      Abort

      If not compiled in debug mode, it crashes with a SEGV.

      3. The crash is because the following line in the XSL:
      <xsl:value-of select="(string($var1_resultof_first/@ID)"/>
      should be:
      <xsl:value-of select="string($var1_resultof_first/@ID)"/>

      Thanks,
      Chad
