preprocessor: Fix column adjustment [PR 99446]
This ICE was because when adjusting a column offset we could advance
into a linemap for a different file. We only checked the next line
map was not for a line further advanced in any file, forgetting that
it could be for an earlier line in a different file. The testcase
needed adjusting as column 512 was unrepresentable, once that was
taken into consideration.
PR preprocessor/99446
libcpp/
* line-map.c (line-map.c): Do not advance to linemaps for
different files.
gcc/testsuite/
* g++.dg/diagnostic/pr72803.C: Adjust expected column.
