I recompiled file FOO, then SETQ(BRKDWNTYPE ''(CONSES TIME)) and (BREAKDOWN BAR BAZ).'
The system tries to compile the breakdown measurement function, and gets a FILE NOT OPEN error for FOO.DCOM.  FOO.DCOM is the value of LCFIL.  Setting that back to NIL (by calling COMPSET explicitly) solves the problem.  But it seems that (1) it is a bug that the variable LCFIL is global, and (2) a bug that the breakdown entry to the compiler gets confused by this global setting.'
