--- Comment #12 from Iain Sandoe <iains at gcc dot gnu.org> 2010-12-01 21:10:51 UTC --- hm. on i686-darwin9 - adding -Wl,-debug simply suppresses the recognition of the source file and dsymutil is not called (a manifestation of PR41751). So there are two things; 1. dsymutil is not being called correctly - depends on what's on the c/l (PR43751) 2. when it is called it looks like the object is being deleted too early.
