I had to look up the difference between XSAVES and XSAVEC: "Execution of XSAVES is similar to that of XSAVEC. XSAVES differs from XSAVEC in that it can save state components corresponding to bits set in the IA32_XSS MSR and that it may use the modified optimization."

In this case it seems like the "modified optimization" is where the bug lies.
