            Bug ID: 80037
           Summary: Bad .eh_frame data in crtend.o
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rth at gcc dot gnu.org
  Target Milestone: ---

Looks similar to PR40332, but targeting alpha.

The cause is gcc writing gas directives for unwind for
__do_global_ctors_aux, and also writing the terminator
for the .eh_frame section via the static variable __FRAME_END__.

This results in one CIE entry after the terminator, causing
ld to complain.

For normal applications, the program still runs ok, although
the lack of .eh_frame_hdr is much less than ideal if c++
exceptions are involved.

However, dejagnu treats this extra output as an error.
So test results for alpha are unusable at present.
