------- Comment #4 from zsojka at seznam dot cz 2010-07-02 08:54 ------- The same assert happens for me at x86_64-linux with testsuite/gcc.dg/sms-3.c, which is much smaller as a testcase:
$ rm *.gcda $ /mnt/svn/gcc-trunk/binary-161659-lto-fortran-checking-yes-rtl-df/bin/gcc -O -fmodulo-sched -freorder-blocks-and-partition sms-3.i -fprofile-generate $ ./a.out $ /mnt/svn/gcc-trunk/binary-161659-lto-fortran-checking-yes-rtl-df/bin/gcc -O -fmodulo-sched -freorder-blocks-and-partition sms-3.i -fprofile-use /mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/sms-3.c: In function 'foo.constprop.0': /mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/sms-3.c:25:1: internal compiler error: in check_cfg, at haifa-sched.c:5241 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Flags are the same, -O -fmodulo-sched -freorder-blocks-and-partition -fprofile-{generate,use} -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41852
