Cannot reproduce on powerpc-apple-darwin7.9.0. Which compiler and optimization
flags did you use?

Still, this doesn't help much. Can you print 40 decimal places of the number
(or the exact binary contents, via %LA)?

The numbers 1.06581e-16 and -1135314207 don't give any clue.
It smells either like a 'long double' returning function was being called
without being properly declared, or like dangerous compiler optimizations.
