             Bug #: 53719
           Summary: can't display x87 stack information
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: tango127@epix.net


Xcode, using gcc 4.5, use to display 80-bit x87 stack values correctly.  Now
all I see is the following (notice no values shown for stack values), although
generated answers are produced correctly and returned to memory variables.  Did
something go "bump" in the night with this newer release?
