Zed - b56e4ff

When compiling app with nightly rust compiler + Address sanitizer, app crashes after opening:

• This is profile.release in Cargo.toml - need to replace entire existing section

[profile.release]
overflow-checks = true
panic = "abort"
debug = true

• compiling zed with address sanitizer + nightly compiler

rustup default nightly
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu
rustup component add llvm-tools-preview --toolchain nightly-x86_64-unknown-linux-gnu
RUSTFLAGS="-Zsanitizer=address" cargo +nightly install --path crates/zed --locked --target x86_64-unknown-linux-gnu

• running app(asan options are needed to see debug symbols - still a little broken, but better than nothing)

export RUST_BACKTRACE=1
export ASAN_SYMBOLIZER_PATH=$(which llvm-symbolizer-18) # also available addr2line, which will run 2 minutes, but will create better backtrace
export ASAN_OPTIONS=symbolize=1
zed

crashes when running with info

@qarmin Thanks for the report!

It seems like this might be something that needs to be reported to wasmtime.
