Comment:
I have created a pull request with the fix, namely changing {{{InteriorNoSync}}} to {{{Interior}}} in McLachlan_BSSN.m which SYNCs ML_Gamma, ML_dtalpha and ML_dtbeta which are exactly the ones that {{{ExtrapolateGamma}}} extrapolates.
I have run the GW150914 gallery example for 256 iterations and verified that the checkpoints at it=0 and it=256 agree (bitwise, other than the parameters group) between executables compiled using {{{InteriorNoSync}}} and {{{Interior}}}.
