Hello! > This is both an ICE and an ABI bug dating back to the implementation of the > 64-bit calling conventions in 1998: for structures larger than 8 bytes and not > larger than 16 bytes containing a FP field in the second half and passed in > slot #15 of the parameter array, the compiler passes the FP field in the %f32 > register instead of on the stack; this results in an ICE for a 'float' and an > ABI bug for a 'double'.
