            Bug ID: 18464
           Summary: unknown value in GNU .note.ABI-tag should not cause a
                    crash
           Product: gdb
           Version: 7.9
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: roland at gnu dot org
  Target Milestone: ---

When an executable has a .note.ABI-tag section with vendor "GNU", and a first
word (ABI tag value) that is unrecognized, GDB gets an assertion failure (calls
internal_error).  This kind of error is inappropriate for diagnosing the
content of an input file.  It should be a simple runtime warning instead.

    Diagnosis of unexpected input (in this case, in an executable file)
    should not crash as if it were a bug in GDB.
