Descrizione

When simple C++ source code is compiled with sanitize and pthreads flags, following error occurs at runtime.

Module.instantiateWasm callback failed with error: ReferenceError: resetPrototype is not defined emcc_pthread_and_sanitize_error

PFA test case WebAssembly.zip to reproduce the above issue. Issue is reproducible on Emscripten version 2.0.7. To compile the test.cc, following command is used. em++ -fsanitize=address -sINITIAL_MEMORY=536870912 -sUSE_PTHREADS=1 -sPTHREAD_POOL_SIZE=1 -sMODULARIZE=1 -sEXPORT_NAME="testWasmModuleReady" --bind --no-entry test.cc -o test.js

Note that, issue is not reproducible if sanitize flag is removed from the compilation.
