You are absolultely right!  I was able to work around the gcc bug by  
making a separate function for Moment comparison and using it instead  
of min():

Moment
min_moment (Moment m1, Moment m2)
{
  return min (m1, m2);
}

OK, I made files with -O1 and -O2 from the files that only differ in  
that the "original" uses min() and the "workaround" uses min_moment().  
 Of the four files, simultaneous-music-iterator-O2-original.s is the  
only one broken (I tested).

Please let me know it you need anything else.
