Game started crashing after experimental build 7002

[ZhilkinSerg]

Something is bad in #22579 (see https://discourse.cataclysmdda.org/t/14649 for details):

 Using 32 bit Windows tiles through the launcher (which I’m running through Wine on a Linux machine) every build past 7002 crashes when it reaches the step “Finalizing Tileset”. It also crashes when I try to switch to a new tileset in the Settings menu in an attempt to see if it was the non-standard tileset I was using that was causing the issue - MShockXotto+ (opaque tree).
 Reverting to build 7001 and changing to Chesthole32 which I know ships standard with the game and then reinstalling build 7004 still results in a crash. Build 7001 continues to run fine.

Pinging @BevapDin :)

According to the posted log file:

17:22:23.748 INFO : Loaded tileset: ChestHole32
17:22:28.137 : Log shutdown.

The log system was shutdown, which means the destructors of the global objects have been run. This indicates the program did not just crash (as by accessing invalid memory), but was closed deliberately (likely via an assert statement).

Can you run the program via the command line and capture the standard error output when it closes unexpectedly?

#22598 may help finding the cause. But assertion failures are typically only printed on the console.

The crash also appears when changing value of "Use tiles" (from "False" to "True" or vice versa) in graphics options when trying to save these options. This only hapens after you tried to start game after you started executable.

I've compiled version with changes from #22598 and started executable redirecting error output to file, but nothing appears there when exception arise.

Command line:
"C:\Source\Repos\Cataclysm-DDA\Cataclysm-Tiles.exe" 1> "C:\temp\out.txt" 2> "C:\temp\err.txt"

when exception arise.

Exception? What exception is it?

Can you run this under a debugger like gdb?

Exception? What exception is it?

I meant crash. No text and I doubt info from eventlog will be helpful:

Trying to setup debug environment now.

Exception thrown at 0x00007FF7CE719A85 in Cataclysm.exe: 0xC0000094: Integer division by zero.

If there is a handler for this exception, the program may be safely continued.

So, I guess the div is equal to 0 in some cases.

Hope it helps - renderer is created with max_texture_width = 0:
