 I just tested with the 3.1 20020404 CVS version: this bug is still
 present and makes it impossible to compile Integration Test Qt/X11 2.3
 on HP-UX 11.00 (hppa1.1). The produced 'uic' binary hangs when
 processing .ui files and makes it therefore impossible to finish the
 build.

>Description:
When compiling the class defined in handler.h and handler.cpp
into a shared library on HP-UX 11.00 (B.11.28 ld) a call to
start() from an application (main.cpp) succeeds but never
returns.

// handler.h
#ifndef HANDLER_H
#define HANDLER_H
class H1 { public: virtual void foo() { } };
class H2 { public: virtual void start() = 0; };
class H12 : public H1, public H2 { public: void start(); };
#endif

// handler.cpp
#include "handler.h"
void H12::start()
{
}

// main.cpp
#include "handler.h"
int main()
{
        H12 hnd;
        H2* h2 = &hnd;
        h2->start();
        return 0;
}
>How-To-Repeat:
g++ -shared -fPIC -o libhandler.sl handler.cpp
g++ main.cpp libhandler.sl
./a.out   (hangs forever)
