Re: [Bug-gsl] SV decomp failure

Hi Steve,

Any chance you'd be willing to dig into the gcc optimization delta
between -O1 and -O2 to determine exactly which optimization causes the
SVD failure on recent OS X systems?  You'd have to dig up a
version-specific set of GCC documentation, but the details should look
something like http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html.

It would be nice to either a) report the problem upstream and/or b)
disable this specific optimization at the smallest possible scope when
detecting OS X along with issuing a compiler warning.
