Law changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at redhat dot com --- Comment #5 from Jeffrey A. Law --- I wonder if this is ultimately the same issue as 61886. In particular I wonder if the fault is somehow caused by the aliasing stuff we're picking up from glibc's header files. I'm not sure the best way to do make that determination. I guess looking at the decls we're trying to emit debug information for in the case where we're faulting in dwarf2out. SImilarly for the case where we fault in the lto streamer. Or perhaps remove the duplicated declarations that create the funky aliases in glibc's headers.
