--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The compiler represents locations and even location ranges as 32-bit integers,
so for normally sized sources can encode both line and column and range
information, but with too many columns or lines gradually loses the
ranges/column information and later the line information as well.
Will defer to David for details.
