Every time.  It breaks "hello world". 

There are several work-arounds that I know of:

	- compile with `--high-level-code', i.e. use the MLDS backend
	  rather than the LLDS back-end

	- compile with `--no-c-optimize', i.e. pass `-O0' rather than `-O2'
	  to gcc.

	- using grade `none.gc' or `reg.gc' rather than `asm_fast.gc' should
	  also work.
