Sometimes a DW_TAG_partial_unit (imported via a DW_TAG_imported_unit) has no children node. That means the the DW_TAG_partial_unit has no sub-tree. In those cases, the dwarf-reader crashes when ctxt.build_die_parent_relations_under tries to record the point at which the sub-tree (which is non-existent here) of the partial unit is imported by the DW_TAG_imported_unit DIE. This patch avoids crashing in those cases. As this problem is reported on libclang-cpp.so (on Fedora 33) which takes "abidw --abidiff" five hours and ~ 20GB of ram to complete at this point (on a power7 box) this patch doesn't have a regression test attached. * src/abg-dwarf-reader.cc (die_has_children): Define new static function. (read_context::build_die_parent_relations_under): Do not try to instantiate an imported_unit_point type for an imported unit with no children node. (imported_unit_point::imported_unit_point): Assert that the imported die has a sub-tree. (imported_unit_point::imported_unit_point): Remove useless spaces.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
