--- Comment #15 from Iain Sandoe <iains at gcc dot gnu.org> 2010-12-01 21:34:19 UTC --- splitting the command into compile and link steps will intentionally remove the dsymutil step - thus making the problem 'go away' ... dsymutil should _only_ be called if there is a source file on the c/l (which would have its object deleted and thus be unavailable for debug).
