Comment # 1 on bug 115 from Johannes Pfau

The problem starts in the frontend, optimize.c(DotVarExp::optimize).
It optimizes 'func(_f(a).i)' into 'func (a)', so it produces a call to func
with an incorrectly typed parameter.

The backend then tries to pass 'a' in floating point register leading to these
strange results.

@Iain do you think this should be fixed in the frontend or in the glue layer by
doing an explicit conversion? I also wonder why the GCC backend didn't catch
this problem, I thought it should know there's a type mismatch between the
function declaration and the actual call?
