           Summary: Need weak linkage on memory functions to make them
                    overridable
           Product: Runtime Libraries
           Version: 1.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: brukman+bugs@uiuc.edu
        ReportedBy: brukman+bugs@uiuc.edu


Some applications may choose to implement their own memory managers, thus
overriding the default implementations of malloc, calloc, free, et al. Thus, we
should have weak linkage on these symbols so that an application can override
them with its own. This was found trying to link together bash.
