Test case:

for ({get 10() {} };;)
    break;

Description:

The test case above triggers a SyntaxError exception with the following message:

for ({get 10() {} };;)
~~~~~~~~~~^
Script Error: SyntaxError: Expected argument list. [line: 1, column: 11]

Numerical getters/setters are allowed by the standard and JerryScript supports them too. It seems that the above glitch only happens if these getter/setters are placed in loops.
