As a workaround, you might try disabling LTO. |

It compiles. I managed to find the relevant code. It appears to be the same piece of code as in #13348, so it's likely the same issue: pub fn sendRequest(conn: *Connection, requests: []chunk.ChunkPosition) !void {
if(requests.len == 0) return;
var data = try main.threadAllocator.alloc(u8, 16*requests.len);
defer main.threadAllocator.free(data);
var remaining = data;
for(requests) |req| {
std.mem.writeIntBig(chunk.ChunkCoordinate, remaining[0..4], req.wx);
std.mem.writeIntBig(chunk.ChunkCoordinate, remaining[4..8], req.wy);
std.mem.writeIntBig(chunk.ChunkCoordinate, remaining[8..12], req.wz);
std.mem.writeIntBig(chunk.ChunkCoordinate, remaining[12..16], req.voxelSize); // ← this line
remaining = remaining[16..];
}
try conn.sendImportant(id, data);
}
This pattern continues, cycling through {1, 2, 4, 8, 16, 32, 64, 128} If I try to print the |

Steps to Reproduce and Observed Behavior
I tried to reduce this error, but I was unable to do that. Whenever I remove too many lines of code the error transforms into #13348. I think the error requires a certain function(+inlined calls) size. Maybe llvm tries to make the function external if it gets too big?
Anyways because I wasn't able to reduce it, here is a link to the exact commit that I tested it with: PixelGuys/Cubyz@d4e9fa2
This is the output that I get:
Expected Behavior
It should compile without an error like in release-small and release-safe and debug.
