Currently Wasm doesn't accept a bare try block with no corresponding catch, catch_all, unwind, or delegate. The spec was recently updated (https://github.com/WebAssembly/exception-handling/pull/157) to allow these in order to make the syntax more regular.
A bare try block is essentially identical to a block instruction.
This bug is for supporting this form of try in SpiderMonkey.

This will need changes in the parser for tests, so I will first implement the new behavior in wabt and wasm-tools before submitting a SM patch.

The proposal spec for exception handling was recently changed
to allow a try block with no catch or delegate clauses:
