Description
wasm-decompile crashes when trying to process this WAT file. Interestingly enough, it works after being processed with wasm-opt.
The full text of the error is:
wabt-main/include/wabt/ir.h:62: const string& wabt::Var::name() const: Assertion `is_name()' failed.

Research direction
Start by reproducing the crash in wasm-decompile with the linked test.zip WAT file, then inspect wabt-main/include/wabt/ir.h:62 and the path that handles the failing variable. Compare behavior before and after wasm-opt processing. Done means the file no longer triggers the assertion and the relevant regression is covered by a test.
