[rcml-devel] Bug in Archive.cpp fixed

[<jx...@ga...>]

  This is the details of the bug I fixed in the writeOut() method of
Archive.cpp, for anyone who is interested.  If you're not interested,
don't worry about it.

  Our previous driver program called readIn() followed by writeOut()
on an Archive.  This was a nice demonstration of the fact that these
methods work.

  At some point, group II was having problems with a core dump.  It
turned out Xerces needs a method called XMLPlatformUtils::Initialize()
called before it can do anything.  Attempts to create a DOM_Document
object cause a segmentation fault and core dump if that method has not
been called.

  For our previous driver, readIn() called this initialization method.
writeOut() did not.  So, the driver worked fine, because the code had
been called, but once we were attempting to do code that did a
writeOut() without ever doing a readIn(), there was a crash and core
dump.

  I put the initialization call in writeOut().  It might be better to
insist that this code must be called in main(); I do not know what
will happen now if someone calls readIn() and writeOut() in the same
program; that will call the initialization method twice.  I'll be
checking.
