I pressume that's because the libs are ev6. > An illegal instruction trap occurs when the processor attempts to execute an instruction which it does not recognize. We attempt to fixup the most common instructions in the kernel (mainly so you can run the acrobat reader binary on older alphas..) However, beast is a 21264a and it supports all valid alpha instructions. So rather than a bug in the opdec code, I suspect that the compiler or linker is emitting bad code, or something else weird is happening. What instruction is causing the trap?
