[m-dev.] Looks like a GCC problem

[Ralph Becket]

I just tried building an unedited, up-to-date version of the main branch
on ceres and got this:

...
../scripts/mgnuc --grade asm_fast.gc      --no-mercury-stdlib-dir --c-debug --no
-ansi   --  -I../boehm_gc -I../boehm_gc/include -I../mps_gc/code  -DMERCURY_BOOT
STRAP_H -DMERCURY_CONF_BOOTSTRAP_H     -c mercury_deconstruct.c -o mercury_decon
struct.o
In file included from mercury_deconstruct.c:28:
mercury_ml_expand_body.h: In function `MR_expand_functor_args':
mercury_ml_expand_body.h:1174: fixed or forbidden register 5 (di) was spilled fo
r class DIREG.
mercury_ml_expand_body.h:1174: This may be due to a compiler bug or to impossibl
e asm

mercury_ml_expand_body.h:1174: Internal compiler error:

                (unspec:SI[ 
                        (mem:BLK (reg:SI 0 %eax) 0)
                        (const_int 0 [0x0])
                        (const_int 1 [0x1])
                    ]  0))
            (clobber (reg:SI 0 %eax))
        ] ) 411 {strlensi+1} (insn_list 85 (nil))
    (expr_list:REG_UNUSED (reg:SI 0 %eax)
        (nil)))
gmake[1]: *** [mercury_deconstruct.o] Error 1
gmake[1]: Leaving directory `/home/ceres/rafe/ws-svars/mercury/runtime'
gmake: *** [runtime] Error 2

Anyone know what the fix for this one is?
