###### JerryScript revision
Commit: 05dbbd13[](05dbbd134c3b9e2482998f267857dd3722001cd7) 
Version: v3.0.0



###### Build platform
Ubuntu 20.04.5 LTS (Linux 5.4.0-144-generic x86_64)



###### Build steps

```sh
python ./tools/build.py --clean --debug --compile-flag=-m32 --compile-flag=-fno-omit-frame-pointer --compile-flag=-fno-common --compile-flag=-fsanitize=address --compile-flag=-g --strip=off --lto=off --error-messages=on --system-allocator=on --logging=on --line-info=on --stack-limit=20
```



###### Test case
``` JavaScript
// poc.js
var t = Function ( ) ; 
t [ Symbol . species ] = Object ; 
var e = new Proxy ( { constructor : t  } , { set : function ( ) { } }  ) ; 
RegExp . prototype [ Symbol . matchAll ] . call ( e ) ; 
```


###### Execution steps & Output

```sh
$ ./jerryscript/build/bin/jerry poc.js
ICE: Assertion '!jcontext_has_pending_exception ()' failed at /jerryscript/jerry-core/jcontext/jcontext.c(jcontext_raise_exception):88.
Error: JERRY_FATAL_FAILED_ASSERTION
Aborted (core dumped)
