I believe that this is caused by make's misuse of execvp after vfork. This normally works but a while ago, malloc was using the wrong value for pagesize on the alpha and this caused problems. I fixed malloc but left the vfork alone; perhaps there are still problems (its in compat.c afaik). -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
