Can you reproduce it with the binaries available from the following link? http://quatramaran.ens.fr/~coudert/gfortran/gfortran-i686-linux-20070518.tar.gz > Program received signal SIGILL, Illegal instruction. > 0x086b7d19 in mpfr_ceil_double () > (gdb) where > #0 0x086b7d19 in mpfr_ceil_double () > #1 0x086b7dd2 in mpfr_get_str_compute_g () > #2 0x086b8160 in mpfr_get_str () > #3 0x0829cb6e in real_from_mpfr (r=0xbf9a8af0, m=0x9c1dc4c, type=0xb7c81b64, > rndmode=GMP_RNDN) at ../../gcc-4.3-20070518/gcc/real.c:5045 It looks pretty much like a MPFR miscompilation to me. Do you use the GMP/MPFR libraries provided by the Fedora project, or do you use custom-made? In the later case, did you run "make check" after compiling them? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31971
