Hmm, not good.

Basically that means that the Mercury compiler has been miscompiled.
It could perhaps be a bug in gcc, or in the assembler.

That kind of thing can be difficult to debug, so I recommend trying grade
hlc.gc, as I suggested earlier, or grade none.gc or reg.gc.
(For the latter two, all you need to do is to use the normal source
distribution and add `GRADE=none.gc' or `GRADE=reg.gc' to Mmake.params.
For hlc.gc, you need different versions of the C files, so as I said earlier
I'll set up a different source distribution for that.)

`hlc.gc' is the grade name normally used by the MLDS-based C code generator.
