Thanks, it solves the problem without the optimize progma for rb_call_super_method, and performance decrease hasn't been observed.

Could you tell me why __forceinline for vm_call_method prevent VC++ to make vm_call_general and vm_call_super_method as the same function?
I couldn't find the reason at <URL:http://msdn.microsoft.com/library/vstudio/z8y1yy88>.

On my box this error is 100% reproducible, but I also know that RubyCI and
RubyInstaller CI don't report this error.
I've heard that nobu reproduced this bug on x86_64-dawrin, but I don't know
the detail of his environment.
