Comment:

 Hello! Thank you for reporting this; it's a script bug in the original
 that relies on the undefined value of an uninitialized variable.

 Fixed in:
 https://github.com/scummvm/scummvm/commit/5a12df7b4b54b572860fce812bc516f6e2cd4d52

 This is so straightforward from looking at the scripts that I didn't
 bother setting up Lighthouse to test this. Please confirm that the fix
 works and I'll close this.

 You saw different behavior because that was a release build. Uninitialized
 variable reads are so common in SCI games that in release builds, we just
 guess a value and proceed in the hopes that the game works, and log a
 warning. In non-release builds it's an error so that it gets the attention
 it needs: an investigation to supply the correct value the buggy script
 needs to work. We've taken care of most of them, every now and again we
 find out about a straggler like this.
