            Bug ID: 19877
           Summary: crash when using objdump -t -C
           Product: binutils
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

Created attachment 9133
  --> https://sourceware.org/bugzilla/attachment.cgi?id=9133&action=edit
binary that makes objdump crash

When I run objdump -t -C on the attached binary, it always segfaults:

    ...

std::move<std::_Any_data&>(std::_Any_data&)
    [1]    14320 segmentation fault (core dumped)  objdump -t
tconcurrent/test/test_co -C

I don't have objdump's debugging symbols, but my debuggers shows a huge stack,
seems like an infinite recursion.

I run objdump 2.26 on debian unstable (I had the bug also with 2.25).
