The sum contains a hash: {"else"=>0, "then"=>0} which can't be parsed by found = sum.map { |k, _| [k[0], k[1] + 1, k[2], k[3] + 1] }

I don't understand the code, but seems like there's a bug in the parsing.

add a p coverage after line 146 to see what is coming in it's supposed to be a branch coverage output, but it seems to be something else

[grosser]

... also from the 897 / 14462 LOC (6.2%) covered. it seems that you have some other coverage tool running, turn that off to confirm that these 2 fighting is causing the issue, then lmk what this other tool is

[mollerhoj]

The other tool is SimpleCov

[mollerhoj]

Disabling SimpleCov fixed the issue.

The input to the function was: {"[:unless, 0, 41, 4, 41, 41]"=>{"[:else, 1, 41, 4, 41, 41]"=>0, "[:then, 2, 41, 4, 41, 26]"=>0}} after disabling, it is now: {[:unless, 0, 41, 4, 41, 41]=>{[:else,1, 41, 4, 41, 41]=>0, [:then, 2, 41, 4, 41, 26]=>0}} Perhaps unpacking the strings would make it possible to run both tools?

[grosser]

things being in strings is the bug afaik so we need to find out where they are coming from what's your SimpleCov version ? ... tried bumping it ? ... tried 0.19.1 which is in the Gemfile.lock here ?
