I sent the wrong copy of the Log file. The right one says:

compiler/dupelim.m:
	Fix a bug that caused a compiler abort in .rt grades when compiling the
	compiler-generated comparison procedure for the type goal_path_step
	in browser/program_representation.m. The problem was that when trying
	to find a generalization of two instruction sequences, we handled the
	case of one instruction sequence starting with a comment that the other
	instruction did not have only when the other instruction sequence
	wasn't empty. With high values of the --compare-specialization option,
	previous invocations of dupelim could create situations in which this
	oversight lead to a compiler abort.

But Simon has, and he says its OK, so I will commit it now.
