The problem occurs in cairo_fixed_from_double(), but I believe there is no mis-compilation. 

I think the function receives a denormalized/weird number (possibly from an uninitialized memory 
address) and floor() silently puts it to 0. In -ffast-math mode the compiler generates the unguarded code 
directly and the output is a huge number in one of the calls.

Still investigating...
