Hi, We're using cmu-cl on a sparc2. We have a program which runs successfully on the mac with Allegro. On running it on cmu-cl we get: Type-error in KERNEL:DATA-VECTOR-SET: 0 is not of type SINGLE-FLOAT If we compile the program and run it, we get: Error in function MACH::SIGBUS-HANDLER. Bus Error at #x701AC8C. Any ideas? Thanks.
