Assertion when debugging a class

[anzenkovich]

Built jerry script with debugger, wrote some js class and started session. Tried to expand "catch" section at first line of class definition, and debugger failed with message:

ICE: Assertion 'ecma_is_value_object (value)' failed at C:\work\jerryscript-master\jerryscript-master\jerry-core\debugger\debugger.c(jerry_debugger_get_variable_type):303.
Error: JERRY_FATAL_FAILED_ASSERTION

Also, I found another case with integer variable with property descriptor. Debugger can't understand that it is number value, but jerry_value_get_type() returns number type;

JerryScript revision

Release 2.4.0

Build platform

Windows, built with cmake on visual studio 2022, with enabled debugger

Test case

Input file test.js:

class MyClass
{
    constructor()
    {
        this.a = 6;
    }

    dd()
    {
        print(this.a)
    }
}

let x = new MyClass();
x.dd();

• run jerry script command line with parameters: --log-level 2 --start-debug-server --debugger-wait-source test.js

• connect visual code debugger

• try to expand "catch" section of variables

• jerry script command line asserts with message:

  ICE: Assertion 'ecma_is_value_object (value)' failed at C:\work\jerryscript-master\jerryscript-master\jerry-core\debugger\debugger.c(jerry_debugger_get_variable_type):303.
  Error: JERRY_FATAL_FAILED_ASSERTION
