Otherwise I'll try to use https://download.01.org/0day-ci/archive/20230711/202307112158.3RFyuSZJ-lkp@intel.com/reproduce Thise are not types that usually appear in C, so perhaps the --lang_exclude=rust isn't working for some reason, i.e. looking at the DW_TAG_compile_unit to se the DW_AT_language. Processing arrays and getting a union type? Interesting :-) - Arnaldo
