Fixed vulnerability oss fuzz 4475563464 (aka libdwarf DW202602-001) reading frame data from
a fuzzed (corrupted) DWARF frame section. See DW202602-001 in
the text file bugxml/data.txt in the source release. The bug first appeared in changes
made 26 January 2026.
Now allows DW_AT_dwo_id and DW_AT_GNU_dwo_id in any DWARF4 or DWARF5 object where such
an attribute makes sense.
Now allows access to a .eh_frame section (APPLE names it __eh_frame) in a Mach-o executable.
Corrects a sanity check of Mach-o objects by eliminating an inappropriate multiply of the sizeofcmds
header field.
