in build.mk, so I assume it has optimization on. Can I simply add

SRC_HC_OPTS += -O0
in the build.mk of the 6.4.2 tree? I'm also assuming that I can just rebuild 6.4.2 with optimization off on the target amd64 box and that I can still use my original .hc files from the i386 machine. Is that true?
Ah, yes, I'd forgotten it was an hc build, so you already have .hc files. They'll do fine - it's just useful sometimes to be able to refer to the same source code that gdb knows about. I think GhcRtsHcOpts += -O0 should do, but you can check it's actually being passed when you rerun make (you'll need to delete the PrimOps object files first). On the other hand, if you mean you're going to do another complete build then you may as well make everything non-optimised now rather than wishing you'd done so later. Thanks Ian
