TinyWasm hangs for `execute/regex_redux` in `wasmi-benchmarks`

[Robbepop]

• This might be connected to TinyWasm fails to instantiate WASI modules with stubs #46 but since this is an execution benchmark and not a startup benchmark I thought it might be different enough to warrant its own issue.
• This is different from TinyWasm traps with unreachable for execute/compression in wasmi-benchmark #47 since TinyWasm traps with unreachable for execute/compression in wasmi-benchmark #47 traps with unreachable whereas regex_redux just hangs indefinitely.

Repro

1. Clone wasmi-benchmarks.
2. Checkout 47886bea65b58afe577ac9c7b502089fd23f4f96.
3. Make can_run return just true to avoid all the filters.
4. Run cargo bench --profile release execute/regex_redux --no-default-features -F tinywasm
5. See that the above command does not behave properly (does not halt).
