> Inter shared library exception handling broken on Linux
> -------------------------------------------------------
>
>          Key: AXISCPP-533
>          URL: http://issues.apache.org/jira/browse/AXISCPP-533
>      Project: Axis-C++
>         Type: Bug

>   Components: Basic Architecture
>     Versions: current (nightly)
>  Environment: GNU specific (as far as I know)
>     Reporter: Tim Bartley

> On Linux, actually on systems where the compiler and common libraries are g++ and gnu
and glibc, exception handling between shared libraries is broken. It is broken because the
same class in different shared libraries is treated differently so that an HTTPTransportException
thrown by a channel library does not match "catch (HTTPTransportException& e)" in the
transport library.
> Refer to http://gcc.gnu.org/faq.html#dso for details.
> The fix is to load the subordinate library with RTLD_GLOBAL flag.
> As far as I know this is GNU specific but may apply to other platforms.
> It's possible that others are not seeing this because the context in which I am running
Axis is from within an application that itself dynamically loads a library that depends on
Axis.
> Cheers,
> Tim
