    Trying to build our emscripten project with 4.0.6 version, during linking phase this happens:

```

With all versions from 4.0.6 - 4.0.2 we get different crash backtrace.
With 4.0.1 (and older) we get multiple errors like this:
```
wasm-ld: error: symbol type mismatch: void xx::someFunction<char [47]>(char const (&) [47])
>>> defined as WASM_SYMBOL_TYPE_SECTION in libx.a(xx.cpp.o)
>>> defined as WASM_SYMBOL_TYPE_FUNCTION in liby.so
```
which is probably related to this: https://github.com/emscripten-core/emscripten/issues/23501 as I think it was fixed in 4.0.2. I haven't yet tried with 3.1.64 where that regression apparently first occurred or 3.1.63 but everything worked nicely at least with 3.1.54 (yeah, very old, I know).

@sbc100 sorry to ping you directly but I think you might be interested of this...
