#15792: MoonbaseCommander multiplayer games crash to console for nonhost players on
game start

    Type:  defect              |     Status:  new
Priority:  normal              |  Component:  Engine: SCUMM
 Version:                      |   Keywords:  multiplayer game crash
    Game:  Moonbase Commander  |
-------------------------------+------------------------------------
 ScummVM version 2.9.0 has a multiplayer crash, (tested with Dec 22 2024,
 Jan 10 2025, and Mar 4 2025 editions). I had previously played
 successfully without this crash with what I thought was 2.9.0 but which
 might have been ScummVM 2.8.1 (April 16 2024), which does not appear to be
 affected.

 - Be non-host, join a lobby hosted by someone else with the same game file
 version on the same WiFi LAN network. When host starts the game, non-host
 clients will crash and drop into the debugger console. Typing 'exit' to
 return to game, as suggested by the debugger console, closes the console
 but does not return you to the game. Host will be waiting for player if
 not going first but can quit at anytime normally.

 {{{
 ScummVM 2.9.0 (Mar 4 2025 22:43:42)
 Console is ready
 Debugger started, type 'exit' to return to the game.
 Type 'help' to see a little list of commands and variables.
 ERROR: (5:2108:0x428C): redimArray: Illegal array pointer not having magic
 number (231,19)!
 }}}

 - Switching which device hosts, wifi networks, or game files (Steam 1.1,
 or Moddb Demo 1.0), has the same crash message.

 Language of game: English

 Versions of game: Moonbase Commander (1.1/Windows/English), game purchased
 from Steam, and the 1.0 Moonbase Commander (Demo/Windows/English),
 available for free on Moddb. Same error messages for either game version.

 OS: Fedora Linux 40 (Workstation Edition), two custom built PCs and a
 Surface Pro 3 laptop. I believe my brother in-law's computers ran Windows
 10/11. Same error messages for any combination of OS'es.

 No save game.

 Versions of ScummVM:
 - 2.9.0 (Dec 22 2024): ERROR: (5:2108:0x428C): redimArray: Illegal array
 pointer not having magic number (231,18)!
 - 2.9.0 (Jan 10 2025): ERROR: (5:2108:0x428C): redimArray: Illegal array
 pointer not having magic number (231,19)!
 - 2.9.0 (Mar 4 2025): ERROR: (5:2108:0x428C): redimArray: Illegal array
 pointer not having magic number (231,19)!
 The only difference in the error message between these editions was the
 referenced magic number: Dec 22 wanted (231,18), while Jan 10 and Mar 4
 both wanted (231,19).

 While composing this bug report I found an older package for ScummVM 2.8.1
 (April 16 2024) on my package manager and was successfully able to connect
 to and launch a lobby without dropping players using this version. I
 believe this was probably the last version I was using before Christmas
 when the crash first appeared for us.
