###### JerryScript revision
Version: v3.0.0

###### Build platform

Linux cqian-s2 5.4.0-148-generic #165-Ubuntu SMP Tue Apr 18 08:53:12 UTC 2023 x86_64 x86_64 x86_64 GNU/Linu

###### Build steps
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
```
let evil = new RegExp();
evil.exec = () => ({ 0: "1234567", length: 1, index: 0 });
"abc".replace(evil, "$'");
```

###### Execution platform
Unnecessary if the same as the build platform.

###### Execution steps
List the steps that trigger the bug.

E.g., if a bug is snapshot-specific:
```sh
build/bin/jerry-snapshot generate -o testcase.js.snapshot testcase.js
build/bin/jerry --exec-snapshot testcase.js.snapshot
```

###### Output
SEGMENT

###### Backtrace
```
