We are trying to track down a numerical problem with unuran that occurs on gcc-4.3. I know that gcc now has a very extensive test suite, and bugs are not common. I'm just wondering, are others finding similar problems with gcc-4.3? We are working on preparing a bug report. The symptoms are: 1) Problem disappears if -O0 2) Problem disappears if a printf is added 3) valgrind is silent -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
