Comment(by zimmerma):
> cf http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46080 to follow the GCC
issue.
the GCC developers say this is not a GCC bug, but
"simply the unpredictability of excess precision arithmetics",
and advise to use -ffloat-store/-fexcess-precision=standard/volatile
float.
Is it possible to use {{{-ffloat-store}}} to build Lapack? It seems to be
a valid option of
{{{sage_fortran}}}:
{{{
tarte% /localdisk/tmp/sage-4.6/local/bin/sage_fortran -v --help | grep
store
...
-ffloat-store Don't allocate floats and doubles in extended-
precision registers
}}}
