Full link command and output with -v appended:
When not using -s MEMORY64=1, the command with --emit-tsd ${PROJECT_NAME}.d.ts compiles and links successfully. However, when using -s MEMORY64=1, it compiles and links successfully without the --emit-tsd ${PROJECT_NAME}.d.ts option, but it reports an error when the --emit-tsd ${PROJECT_NAME}.d.ts option is added.

There were some change to the memory64 spec relatively recently. You'll need set NODE_JS in your emscripten config use node 24.

[alpinebuster]

After updating the NODE_JS configuration to node 24, with all other configurations and commands remaining the same, a new error occurred. The error is as follows:
