[heymanMC]

System Information

• Minecraft Version: 1.18.1
• Canvas Version: 1.0.2256

How to trigger the behavior

Two ways:

1. • Start MC with the resourcepack enabled

or

2. • Start MC with no resourcepacks enabled
   • Log onto a singleplayer world
   • Enable the resourcepack from the menu
   • Game will crash

FwuffyPe†sOwO~#7236 also said they experience this with this pack:

I am going to try disabling parts of the pack (Default Improved) to try to get the game to load. Anything found will be commented here.

I get this error from time to time after enabling the resourcepack in game if it helps.

i've suffered a similar fatal jvm crash with the drink beer mod, only relevant info i'm getting in the log is this:

Process crashed with exitcode -1073740940.

since the errorcodes are different, they could be for different reasons, but since this is the only reason i can think of for why the crash happens between these two mods, i'll post it as a comment under this issue, because i didn't want to make a dupe issue if they are for the same reason.

it did also give the same jvm fatal error message shown here at times, but it didn't happen all of the time.

[heymanMC]

More insight:
If I remove just the entity folder from Default Improved, the game is able to load just fine and works.

[Pikalyx]

I get the same issue myself with the texture pack https://www.curseforge.com/minecraft/texture-packs/jicklus

Log:
https://paste.ee/p/Ac9YY

had the same exit code of -1073740940 as well if it helps.

[Pikalyx]

Removing the entity folder also works for my machine.

[heymanMC]

Figured out the specific textures causing the issue:

assets/minecraft/textures/entity/shield_base.png
assets/minecraft/textures/entity/shield_base_nopattern.png

Removing these textures from the pack fixes the crashing.
So, it looks like something is wrong when stitching the atlas for the base of a shield for some reason.

These textures may be redundant in the latest 1.18 resource pack version since there is a entity/shield/base.png texture however, the game should not crash for redundant textures.

[jardhu]

@heymanMC, can you try setting "groupAnimatedSprites": false in the Canvas config and reloading the resource pack(s) in question?

[spiralhalo]

As jardhu said, this seem to be caused by Group Animated Sprites. Interesting that certain sprites are causing it though, certainly will be helpful in fixing this issue.

[jardhu]

I suspect it's something to do with texture size. Any texture in this directory that is larger than 32x32 causes crashes upon the game loading, reloading resource packs, entering a world, generating chunks, etc.

The errors are almost always heap corruptions and access violations deep inside C libraries, which hinted to me that there's some kind of upper-level memory corruption going on.

[getchoo]

i've been able to recreate this with faithful 32x as well as bare bones; disabling group animated sprites fixed it. i got a pretty detailed crash log from the jre here with a similar access violation from other reports. i like this project a lot but this has honestly been a bit frustrating until i found a fix here. i hope maybe the log can help a bit :)

[jardhu]

According to @getchoo's log this crash is occurring at the MemoryUtil.memCopy call here.

Definitely some kind of memory corruption, but I don't know how neither Minecraft's texture memory nor the combined sprite algorithm work so I can't reasonably debug this any further.

[getchoo]

taking a wild guess here, but it seems like the pointers are just being miscalculated with specific sprites - thus the access violation. to be more specific, i think the culprit could be a precision error from converting the ints srcY and destY to longs (seen here and here). maybe with larger sprites the precision isn't enough or something?

edit: wasn't thinking, it would be the destination parameter of memcopy; so the issue causing the crash would most likely be in the conversion of destY, but a similar error could be happening with srcY if that's the case - which would also copy the wrong area of memory
