We are currently trying to use https://github.com/danmayer/coverband to measure production code usage, and that gem relies on https://ruby-doc.org/stdlib-2.6.6/libdoc/coverage/rdoc/Coverage.html to actually measure when code is executed.

Unfortunately, when I enable SCOUT_AUTO_INSTRUMENTS, it stops reporting any coverage and I think it's because this: https://github.com/scoutapp/scout_apm_ruby/blob/master/lib/scout_apm/auto_instrument/instruction_sequence.rb#L19 rewrites the code, thus preventing it from being measured by Coverage?

Any advice?

Thanks!
