<backtrace>

Start by reproducing the crash while compiling wasmtime-39.0.1/src/lib.rs with the reported rustc flags, comparing the default stack size with RUST_MIN_STACK=67108864. Then inspect the reported rustc_resolve::Resolver::resolution_or_default path and the resolver_for_lowering_raw query. Done means identifying the cause of the index-out-of-bounds panic and validating a compiler fix against this reproduction.
