I explored this area in the repository by writing a stress test code for realloc + wasm workers + aborting malloc=0 + memory growth, which can be found in https://github.com/emscripten-core/emscripten/pull/19465/files#diff-02c8c2b081a2137723784e50ae5aedd7a2df1ac8dc3cfcb4ad6ac9eb8137f0fb , but was not able to coax out an issue.
If you are still keen, one approach might be to try to mutate that test case to look like your scenario, if you might be able to get the test to show the same issue you were seeing.
