Pure virtual function called - when using XObjectPtr and XPathEva luator

["Ramakrishnan, Anantha Umamaheswara (Anantha)** CTR **" <ar...@lucent.com>]

Hi
     My function(goToContextStruct) using XPathEvaluator.selectSingleNode to
navigate through an XML 
and then using theEvaluator.evaluate to get an XObjectPtr object from which
I am getting the string data.

I am calling this function multiple times in my program.
After nearly hundred successful calls(sometimes after 92 calls, sometimes
after 115 calls) , I am getting an error : 
	Pure virtual function called
a core dump follows.

gdb stack trace says :

#6  0x60740 in __1cKxalanc_1_8KXObjectPtr2T6M_v_ ()
#7  0x5fa80 in
__1cIMIMUtilsRgoToContextStruct6MnDstdMbasic_string4Ccn0BLchar_traits4Cc__n0
BJallocator4Cc_____b_ ()
........
........
........

The funny part is that my classes don't use inheritance at all !

Could this indicate a bug in Xalan-C++ ?
Or is there a problem with the way I am using the Xalan classes.

Any solution or workaround will be of great help !

Thanks,
