            Bug ID: 27699
           Summary: Assertion failure on armv7l
           Product: libabigail
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: default

  Target Milestone: ---

I am using abidw on a Raspberry Pi 4, Raspbian Buster. When I compile the
igraph project (https://github.com/igraph/igraph/) in debug mode, with
link-time optimization, into a shared library, and call

abidw src/libigraph.so

it crashes with the following:

abidw: abg-dwarf-reader.cc:13241: void
abigail::dwarf_reader::finish_member_function_reading(Dwarf_Die*, const
function_decl_sptr&, const class_or_union_sptr&,
abigail::dwarf_reader::read_context&): Assertion `__abg_cond__' failed.

This is libabigail 1.8.0 that I compiled myself from sources. However, the =
same
crash happens also with libabigail 1.5.0 which is included in Raspbian Bust=
er.

It only happens when I compile this project with link-time optimization.
Compiler is: gcc (Raspbian 8.3.0-6+rpi1) 8.3.0=20

I cannot reproduce the same issue on Ubuntu 20.04 on x86_64.

I am happy to provide the .so file, or more specific information about how I
compiled igraph to obtain the offending .so file.
