Description
I ran into an assertion when running twiggy top on a multithreaded wasm module (attached here)
$ twiggy top raytrace_parallel_bg.wasm
thread 'main' panicked at 'should not parse the same key into multiple items', /home/alex/.cargo/registry/src/github.com-1ecc6299db9ec823/twiggy-ir-0.6.0/./ir.rs:53:9
