--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
current RIP was 00007FFF08523EC8.

> 00007FFF08523EC8  mov         qword ptr [rsi],rax

rsi pointed to a invalid address.
rsi should point to a address to where the return value (JSValue) will be stored.

rsi is a callee saved registers.
It seems that one of the functions called from JITCode::execute destructed rsi.
