Matt Hoyt resolved XALANC-447:
------------------------------
Resolution: Fixed
Robert,
Thank you for the bug report and investigation. It uncovered a couple of
issues:
After some digging, I managed to reproduce the exact bug when using a simple
input document containing only a root element.
1) When an exception occured, an assertion/abort was generated because the
XObjectPtr stack still had references to XObjects after the engine reset had
freed the allocators. This was fixed by clearing the stack before resetting
the engine.
2) This example should not cause any exception. The source of the exception
was caused when an <xsl:for-each> element contained any <xsl:variables> but
when executed did not select any children the variable stack became
inconsistent. This was fixed by checking to see if any children were executed
before popping values off the stack.
Please try the latest CVS.
