Bug ID: 33858
Summary: Object Attributes v2 memory leaks
Product: binutils
Version: 2.47 (HEAD)
Status: NEW
Severity: normal

framework patch
Object Attributes v2 code doesn't free memory on lists attached to
elf_obj_attr_subsections. This results in direct leaks under valgrind and asan
when the bfd and tdata memory is freed. Fixing this isn't quite so simple as
the attached patch, because lists are merged and copied resulting in multiple
pointers to the same memory. Work needs to be done to remove an item on one
list when adding it to another list.
