            Bug ID: 22015
           Summary: abidw failing with Assertion `i !=
                    ctxt.die_tu_map().end()' for mongodb shared libraries
           Product: libabigail
           Version: unspecified

          Severity: normal

Library that reproduces the assertion failure

- OS: Ubuntu 16.04
- Compiler: clang 3.9, from system packages
- abidw built from source at revision bd863916ab46da6cf3b3dc3fadee0c5029139538
- elfutils built from source at revision

I'm getting the following assertion on many shared libraries generated as part
of the build of MongoDB:

abidw: abg-dwarf-reader.cc:11841: abigail::ir::scope_decl_sptr
abigail::dwarf_reader::get_scope_for_die(abigail::dwarf_reader::read_context&,
Dwarf_Die*, bool, size_t): Assertion `i != ctxt.die_tu_map().end()' failed.

I've attached a library that exhibits the problem.

You can repro this by building the mongodb master branch
(https://github.com/mongodb/mongo) as follows:

$ python ./buildscripts/scons.py -j18 --link-model=dynamic --dbg=on --lto
ABIDW=<path-to-abidw> all

Or by running abidw against the attached file

$ ~/opt/bin/abidw libboost_iostreams.so
abidw: abg-dwarf-reader.cc:11841: abigail::ir::scope_decl_sptr
abigail::dwarf_reader::get_scope_for_die(abigail::dwarf_reader::read_context&,
Dwarf_Die*, bool, size_t): Assertion `i != ctxt.die_tu_map().end()' failed.
Aborted (core dumped)
