Description
I'm trying to shrink my WASM output, and wanted to try panic="abort", but I'm getting an error saying that the core crate requires the unwind panic strategy.
Rust version: 1.90.0 (stable)
Target: wasm32-unknown-emscripten
Cargo invocation:
RUSTFLAGS=-Csymbol-mangling-version=v0 cargo build --release --target=wasm32-unknown-emscripten Compiler output:
Compiling remglk v0.1.0 (/src/remglk/remglk) Compiling remglk_capi v0.1.0 (/src/remglk/remglk_capi) error: the crate `core` requires panic strategy `unwind` which is incompatible with this crate's strategy of `abort` error: could not compile `remglk_capi` (lib) due to 1 previous error In my searches I haven't seen anyone have panic strategy troubles for the core crate before, which I take either means that I'm doing something very weird with my setup, or that wasm32-unknown-emscripten is not used much any more.
I've tested, and panic="abort" did work in 1.89, and it works in 1.90 on x86_64-unknown-linux-gnu. So this seems particular to the Emscripten target, and it's a new regression.
