Lines 409 to 439 in 1dfe990 Does your version of library JS also contains this symbol? |

Yeah git clone https://github.com/emscripten-core/emsdk.git
./emsdk/emsdk install 3.1.68
./emsdk/emsdk activate 3.1.68
source ./emsdk/emsdk_env.sh
# install rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y

rustup target add wasm32-unknown-emscripten
echo "fn main(){}" > a.rs
rustc -Copt-level=z a.rs -o a.js --target=wasm32-unknown-emscripten |

There have been a lot of bugs when the caller passes `-lc` over the years. For example it crashes if we do: ``` emcc -lc -sDISABLE_EXCEPTION_CATCHING=0 -sMIN_SAFARI_VERSION=150000 ``` Rust likes to pass `-lc`. Let's drop it and stop causing trouble for Rust. Resolves emscripten-core#22758, emscripten-core#22742 and would have resolved emscripten-core#16680 if it hadn't disappeared first.

You need rust and the emscripten target installed.
rustup target add wasm32-unknown-emscripteninstalls the emscripten target if you use rustup.Fails with:
If we minimize the failing emcc link command, it looks like:
If I remove either
-Ozor-lcthen it succeeds. If I passEMCC_DEBUG=1and look at the contents oftmpogw1glcz.jsonit looks like:Details
