It seems that many of the unit test failures happen when the function henon
is involved. This function computes the Henon map with a default transient
initial period of 10000 samples. The computation in the henon function is
iterative and my guess is that the results are sensitive to the
architecture-specific floating point representation. Would -ffloat-store
help here?
-ffloat-store sometimes matters on i386, but on most architectures it
is a complete nop.
