    DW_LLE_start_length =3D 0x08,

Didn't make it into binutils until 2.35:
https://sourceware.org/pipermail/binutils/2020-November/114140.html


gdb support went in at
https://sourceware.org/git/?p=3Dbinutils-gdb.git;a=3Dcommit;f=3Dgdb/dwarf2/=
loc.c;h=3D3112ed9799124edf4d1f9c903da0d59f5a4ca102

Which did not make it until gdb 10.0.=
