Your example works if "bp" is not a register.  If it is (minimal
bug code: "f(){register float *p;if(*p++)"), I get

	HEY! cookie = SCC
	node1) U*, float, NOPREF, SU = (0,0)
	    node2) ++, PTR float, NOPREF, SU = (1,0)
		node3) REG a5, PTR float, NOPREF, SU = (0,0)
		node4) ICON #4, int, NOPREF, SU = (0,0)
	, line 2: compiler error: floatcode got a tree it didn't expect

which clearly indicates that the floating point code generator
doesn't handle INCR nodes.  (Nor ASG MINUS, by the way.)  Of course
these occur only on "float *", not "double *"....

(I like the error message; it shows exactly what the problem is.
Now if only we had the source....)
