test failures with ruby3.1

[boutil]

Hi,

In Debian, we get 4 failing tests with ruby3.1. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019612.
The bug is about 2.4.8, but the same happens with 2.4.13

  1) Failure:

It seems that the format of the backtrace changed with this new version of Ruby, and that the method must_raise_on_line is not fit for this modification.
