[libxml++] Problem catching parser exceptions on Win32

[Tony Cowderoy <tony cowderoy co uk>]

I have a problem catching parser exceptions on Win32 
(XP/msys/mingw/gcc).  This is causing me difficuties with error handling 
in libglademm and also when using libxml++ directly.  I've reproduced 
the problem in a minimal example.

The following code catches an exception OK when built and run on Debian 
etch, but fails to do so when built and run on XP SP2.  Does anyone have 
any idea why or what I can do to fix it?

Here's the code:

include <iostream>
#include <libxml++/libxml++.h>

int main (int argc, char *argv[])
{
   xmlpp::DomParser parser;
    try {
      parser.parse_memory("xxxxxxxxx<root_node/>");
    }
    catch (...) {
        std::cerr << "Caught an exception from the parser." << std::endl;
    }
}

On Debian etch, the output is:

> Entity: line 1: parser error : Start tag expected, '<' not found
> xxxxxxxxx<root_node/>
> ^
> Caught an exception from the parser.

On Win XP/msys, the output is:

> This application has requested the Runtime to terminate it in an unusual way.
> Please contact the application's support team for more information.
> Entity: line 1: parser error : Start tag expected, '<' not found
> xxxxxxxxx<root_node/>
> ^

Note that the exception hasn't been caught this time.

The Win 32 environment is:
Windows XP SP2
MSYS 1.0.11
MinGW 5.1.3
gcc 3.4.5
Gtk 2.10.11-1 (from gladewin32.sourceforge.net)
gtkmm 2.10.11-1 (from ftp.gnome.org)

The Debian build environment uses gcc 4.1.2 .

The build command line on Debian etch was:

> gcc xmlpp_test01.cc -o xmlpp_test01 `pkg-config libxml++-2.6 --cflags --libs`

Replacing gcc with g++ works OK as well.

On Win XP/msys it was:

> g++ xmlpp_test01.cc -o xmlpp_test01 `pkg-config libxml++-2.6 --cflags --libs`

Running it as gcc instead causes problems.

Any help will be much appreciated.
