 Priority:  Normal        |  Milestone:

--------------------------+----------------------------
 Qt4 in `qdebug.h` has a chunk of code which sends GCC into ICE:
 {{{
     inline ~QDebug() {
         if (!--stream->ref) {
             if(stream->message_output) {
                 QT_TRY {
                     qt_message_output(stream->type,
 stream->buffer.toLocal8Bit().data());
                 } QT_CATCH(std::bad_alloc&) { /* We're out of memory -
 give up. */ }
             }
             delete stream;
         }
     }
 }}}

 What happens:

 Is there something wrong with Qt4 code here or is it actually a bug in
 GCC?
