# Before parse.c 1.639 from 2022-01-08, PrintStackTrace and other diagnostics
# printed a wrong line number, using the last line before the loop body, while
# it should rather be the line number where the .for loop starts.
#
# Before parse.c 1.643 from 2022-01-08, PrintStackTrace tried to be too clever
# by merging stack trace entries, printing confusing line numbers as a result.
