Descrição
We're testing long-lived component instances created with ComponentizeJS. After some number of calls to an instance we start getting failures, wasm traps such as unreachable or uninitialized value. The number of calls before a failure seems to vary based on the functions called and the data returned, but it consistently fails given the same pattern of calls.
I've created a test case using the ComponentizeJS testing here: https://github.com/bytecodealliance/ComponentizeJS/compare/main...pvlugter:ComponentizeJS:repeated-calls
Which fails after 1805 calls with:
```
RuntimeError: failed on attempt [1806]: null function or function signature mismatch

Direção de pesquisa
Start with test/cases/repeated-calls/test.js and the linked ComponentizeJS repeated-calls test case, then inspect the generated test/output/repeated-calls/repeated-calls.js around the reported call path. Run the case to reproduce the failure after repeated instance calls. Done means the same call pattern completes without the reported wasm trap.
