>Description:
A problem exists where global/static objects are not getting constructed in a shared library that is dynamically loaded using HP 'shl_load' interface. If the library is linked during compile time, the objects are constructed without problem.
The shared library and executable are both compiled using g++ 3.2. Here are the commands used to build,which are provided in a Makefile:

        g++ -fPIC -c test_shared.cpp -o test_shared.o
        g++ -shared -fPIC test_shared.o -o libtestsh.sl
        g++ -fPIC -lpthread -ldld -L. test.cpp -o test

This problem seems to be related to HP-UX specific. The testcase provided works on Linux without errors.

Please advise.
>How-To-Repeat:
use testcase on a HP-UX 11.0 system

State-Changed-Why:
    Problem fixed in 3.3 and 3.4 under hpux11.
    <http://gcc.gnu.org/ml/gcc-patches/2003-01/msg00208.html>.
    
    No fix is possible using earlier versions of hpux.  A user
    must arrange to explicitly call the shared library initializer when using shl_load.
