I installed the latest GPC beta (gpc-19990118) on a DEC3000/800 (Alpha) running Digital UNIX 4.0B and was able to compile and install without difficulty. However, anything I compile gives me the following error message when run: internal error: duplicate constructor No coredump or anything else is produced. I compiled on top of GCC 2.8.1. 128 MB of RAM is installed. I uninstalled the DEC Pascal runtime to insure no conflict. John L.
