SHT_GROUP
This section defines a section group. A section group is a set of sections that
are related and that must be treated specially by the linker (see below for
further details). Sections of type SHT_GROUP may appear only in relocatable
objects (objects with the ELF header e_type member set to ET_REL). The section
header table entry for a group section must appear in the section header table
before the entries for any of the sections that are members of the group.
How were __sancov_cntrs sections generated?
