Thanks for filing this bug report.

Thanks, but I think it's a separate issue.
The backtrace shows the ICE is at line 1388 of input.c, which would suggest
it's a failure of this assertion:
gcc_assert (line_width >= (start.column - 1 + literal_length));
where it earlier called:
const char *line = location_get_source_line (start.file, start.line,
&line_width);
I *think* what's happening is that that line is reading the latest on-disk copy
of the input file, but using location information based on the state of the
input file when the .i file was created.
I'm not able to reproduce this yet, but I'll try to based on the above theory.
