No.

The code fails in grades asm_fast.gc.par and reg.gc.par.
It works fine in none.gc.par. 
It also works fine in asm_fast.gc.par and reg.gc.par
if you disable GC using `MERCURY_OPTIONS=-x'.
Examining the output with GC debugging enabled
(delete -DSILENT from boehm_gc/Makefile, and use
`MERCURY_OPTIONS=-dG') shows that it seems to crash
fairly shortly after the first real garbage collection.
The symptoms are definitely some kind of memory corruption.
