Hi All!,
I am experiencing a confusing problem!
I am developing a windows application that makes use of the Xerces
compiler, I am overriding the SAX error handler interface in order to
intercept exceptions from the parser. Within the error handling method I
transcode the systemID in order to get the filename. I am then responsible
for deleting this area of memory when I have finished with it, but the
problem is that as soon as I call delete the program crashes!
It would appear that there is a problem with the allocation of memory.
Is this a bug? or am I missing the point on how to handle error exceptions
?
Many thanks for your time
Neil
