SCI: Betrayed Alliance v1.3.2: Uninitialized read

[dfsgand]

ScummVM version: ScummVM 2.9.0git4897-g054e28f118a on Linux (amd64, Debian 11.9)

Game: Betrayed Alliance v1.3.2, ​https://github.com/Slattstudio/BetrayedAllianceBook1/releases/tag/release-v1.3.2

Upon being given control after choosing New Game and watching the intro, selecting the "Notes" option from the "Character" menu opens the ScummVM debug console with an uninitialized read message. Exiting from this console crashes the game.

The game supports running a native SCI interpreter through DOSBox. Doing so works: selecting the Notes option shows a dialog box instead of crashing the game. (See the attached screenshot.)

Scummvm's terminal output is:

WARNING: SDL mixer output buffer size: 512 differs from desired: 1024!
