IRIX and nonexistant schemas

           Summary: IRIX and nonexistant schemas
           Product: Xerces-C++
           Version: 2.1.0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Validating Parser (Schema) (Xerces 1.5 or up only)
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: woody@hackswell.com


IRIX 6.5 will consistantly SIGSEGV or SIGBUS when cleaning up after it
encounters the fatal error of a schema file not being able to be opened. (in my
case via http).  This of course assumes schema validation is turned on. :)

Seems to be a bug where ~XMLReader is getting called too many times,
particularly from ReaderMgr::reset.  In this case it gets reset once, then the
fCurReader is passed to it again with a non-null, and non-valid value.  For
example, calling ~XMLReader on a fCurReader who equals 0x4 will definitely cause
a SIGSEGV. :)

SOMETHING is overwriting the fCurReader in ReaderMgr to a completely invalid value.

This is reproducable with PParse -n -s -f    and any xml file that calls an
invalid schema on IRIX.   Seems to clean up fine in Linux.
