The problem here was that we generated C calls with expressions involving R1 etc. as parameters. When some of the R registers are also C argument registers, both GCC and the native code generator generate incorrect code. The hacky workaround is to assign problematic arguments to temporaries first; fortunately this works with both GCC and the NCG, but we have to be careful not to undo this with later optimisations (see changes to CmmOpt).
