            Bug ID: 23415
           Summary: binutils-gdb/gdb/ia64-tdep.c:2664:16: error: too many
                    arguments to function target_read_alloc
           Product: gdb
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

gdb fails to build on ia64 (looks like API to read data from core files changed
slightly). Current binutils-gdb git master:
