Since this is a compiler bug, I'm not sure what is the best thing to do at present. Let me run the full test suite of Sage first, having built PARI with -O0 and see what happens. If that works, I will just need to figure out how to build only bezout* with -O0 (or -O1). I'm guessing the best thing the PARI devs could do at this point is report a bug to Apple (maybe Justin Walker could file a bug report to Apple about their compiler)? Also, suggestions about how to properly build only *one* file with -O1 would be helpful. -- William > > John > > >> >> -- William >> >> -- >> To post to this group, send an email to sage-devel@googlegroups.com >> To unsubscribe from this group, send an email to >> sage-devel+unsubscr...@googlegroups.com >> For more options, visit this group at >> http://groups.google.com/group/sage-devel >> URL: http://www.sagemath.org > > -- > To post to this group, send an email to sage-devel@googlegroups.com > To unsubscribe from this group, send an email to > sage-devel+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/sage-devel > URL: http://www.sagemath.org -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
