Summary: TwoPunctures: fix segfault and miscalc when using single precision
When using EinsteinInitialData/TwoPunctures with CCTK_REAL set to
single-precision memory-access errors and incorrect results were
encountered. The incorrect results could potentially affect
double-precision code too.
The memory access errors occur due to double* / CCTK_REAL* confusion.
The incorrect results are due to rounding errors in
PunctTaylorExpandAtArbitPosition that push an acos argument outside of
[-1,1]. Though this was encountered with single-precision code, perhaps
it could occur with DP code too.
This fixes ticket 1894.
