How to increase the memory size of the interpreter in wasm-bindgen-wasm-interpreter?

[TheVeryDarkness]

Summary

I've run out of the memory (the field mem in Interpreter) when generating interface with wasm-bindgen (called from wasm-pack) for my project. Maybe my project is too big? Will it be okay to simply extend the memory size when storing to a place that is not in the vector?

Additional Details

The program panicked at wasm-bindgen-wasm-interpreter-0.2.87/src/lib.rs:311:32: index out of bounds: the len is 1024 but the index is 375022

Run with wasm-pack build.

This seems like a rather big increase to me, more then two orders of magnitude. Do you know what exactly is causing this?

Cc #3162.

Let me have a fork, increase the capacity and test it in my program.

I have a similar issue when linking emscripten's libc (compiled to wasm32-unknown-unknown).

Here's a minimal reproduction repo (just run ./build.sh - sorry, only tested on macOS for now. Assumes cargo and wasm-bindgen are in PATH): https://github.com/gustavohenke/wasm-bindgen-libc-bug

(in fact, I hit #3315 unless __environ.c is ignored)

I can go ignoring several files and the issue just moves around; it seems to have to do with files that depend on CURRENT_LOCALE, which is the case of strftime, used in the above example repo. https://github.com/emscripten-core/emscripten/blob/5b24a09de582f3943d75aa6af9be36ba719c08c0/system/lib/libc/musl/src/internal/locale_impl.h#L40

Actually, simply increase the capacity won't work, as some other errors will show up.

In light of this I will close this issue.
