## JavaScriptCore Version
1f2d2a92eeb831bedd01bbb5b694a0e29fa9af81

## Build 
Ubuntu 20.04.2 LTS (Linux 5.15.0-67-generic x86_64)
./Tools/Scripts/build-jsc --jsc-only --debug --build-dir=asan --cmakeargs="-DCMAKE_C_COMPILER='/usr/bin/clang' -DCMAKE_CXX_COMPILER='/usr/bin/clang++' -DCMAKE_CXX_FLAGS='-g -O3 -fsanitize=address'"

## Testcase and  Execution steps

```
var buffer = new Uint8Array([0,97,115,109,1,0,0,0,1,160,128,128,128,0,4,80,0,95,1,127,0,80,0,94,123,1,80,0,96,3,127,127,127,1,127,96,6,127,112,107,103,101,107,112,127,0,3,130,128,128,128,0,1,2,4,133,128,128,128,0,1,112,1,1,1,5,132,128,128,128,0,1,1,16,32,13,131,128,128,128,0,1,0,3,7,136,128,128,128,0,1,4,109,97,105,110,0,0,9,139,128,128,128,0,1,6,0,65,0,11,112,1,210,0,11,10,148,128,128,128,0,1,18,0,6,127,65,112,7,0,26,26,26,26,26,1,11,179,168,103,11]);
var module = new WebAssembly.Module(buffer);
var instance = new WebAssembly.Instance(module);
```
./bin/jsc  --useWebAssemblyGC=true --useWebAssemblyTypedFunctionReferences=true testcase.js

## Output
SHOULD NEVER BE REACHED
