GUI: Segmentation fault when clicking on Options in the ScummVM GMM

Reported by: antoniou79 Owned by: antoniou79
Priority: normal Component: Common
Version: Keywords: freeze, segmentation fault, GMM, Options
Cc: Game:

Description (last modified by antoniou79)

Edit: This actually seems to be a more general regression, since the bug occurs when clicking on Options on the ScummVM GMM (in-game), regardless of the game engine.

This happens on a local build 2.6.0git from master and on the recent daily on Windows 10 x64 (windows-x86-64-master-87b7ddc7).

Original steps to reproduce (first noticed while testing Ultima 8):
This is with Ultima 8 Gold Edition/DOS/English (GOG release).

The bug does not happen in ScummVM 2.2.0 or in 2.5.0 stable releases. It seems to be a regression.

Steps to reproduce.

  1. Launch Ultima 8
  2. Start a new game, give a name to your avatar and reach the first gameplay screen.
  3. Press Esc to bring up the in-game native menu.
  4. Choose "4. Options".

Bug Result: The game either freezes or exits with a segmentation fault.
Expected result: This options should bring up the ScummVM GMM options menu (this is how it works in 2.5.0 and 2.2.0).

It turns out the issue was not specific to Ultima 8, but to "Options" from the in-game ScummVM GMM menu, regardless of the game engine.

I've committed a fix for this:

Probably we should cherry-pick it for 2.5.1, if we also cherry-pick the related previous commit (
