Memory Leak when parsing input with an undefined encoding

Key: XERCESC-1480
URL: http://issues.apache.org/jira/browse/XERCESC-1480
Project: Xerces-C++
Type: Bug
Versions: 2.6.0
Environment: Reproduced on:
Solaris 8: SunOS 5.8 Generic_117350-06 sun4u sparc SUNW,Sun-Fire-V240
Suse Linux 9.2: Linux 2.6.8-24.14-default #1 Tue Mar 29 09:27:43 UTC 2005 i686

Reporter: Tito Pena
Priority: Minor
When creating an XMLReader object with an InputSource which has an unknown
encoding, a TranscodingException is thrown, leaking the fPublicId, fSystemId
and fEncodingStr members. This occurs on lines 261 and 357 in XMLReader.cpp.
I am including a diff -C3 patch for the fille.
