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.
Thanks for your quick reply. Are there other sources of differences in
the representation of float numbers across the architectures, that might
explain the different results in the henon function?
