Build platform

Linux-4.15.0-62-generic-x86_64-with-Ubuntu-18.04-bionic

Build steps

./tools/build.py --clean --debug --compile-flag=-fsanitize=address \
--compile-flag=-m32 --compile-flag=-fno-omit-frame-pointer \
--compile-flag=-fno-common --compile-flag=-g \
--strip=off --system-allocator=on --logging=on \
--linker-flag=-fuse-ld=gold --error-messages=on --profile=es2015-subset

Test case

var Base = function ( ) { }.bind( );
Object.defineProperty ( Base , 'prototype' , { get : function ( ) {$} } ); 
class C extends Base { }

Note: although the assert message is the same as in #3106, but the test cases seem quite different.

Output

Script Error: TypeError: Class extends value does not have valid prototype property.
ICE: Assertion 'JERRY_CONTEXT (jmem_heap_allocated_size) == 0' failed at jerryscript/jerry-core/jmem/jmem-heap.c(jmem_heap_finalize):106.
Error: ERR_FAILED_INTERNAL_ASSERTION
