Arseny Solokha <asolokha at gmx dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED |--- --- Comment #11 from Arseny Solokha <asolokha at gmx dot com> --- Actually, testcase from comment 0 still ICEs for me, as well as its slightly modified version: subroutine foo() implicit none integer :: x integer :: a(0:1) 10 x = x + 1 20 if ((a(x) .ne. (-1)) .or. (a(x + 1) .ne. (-1))) then x = x + 1 go to 20 end if call undefined() go to 10 return end subroutine foo % gfortran-13 -O1 -fpeel-loops -funreachable-traps -c comment0.f during GIMPLE pass: cunroll comment0.f:1:23: 1 | SUBROUTINE YYPARS(LSTACK,YYPS,YYSTAT) | ^ internal compiler error: in check_loop_closed_ssa_def, at tree-ssa-loop-manip.cc:645 0x7804b7 check_loop_closed_ssa_def /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-manip.cc:645 0x10fc384 check_loop_closed_ssa_bb /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-manip.cc:659 0x10fd746 verify_loop_closed_ssa(bool, loop*) /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-manip.cc:695 0x10fd746 verify_loop_closed_ssa(bool, loop*) /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-manip.cc:679 0x10e5461 tree_unroll_loops_completely /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-ivcanon.cc:1499 0x10e54d1 execute /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-ivcanon.cc:1603 0x10e54d1 execute /var/tmp/portage/sys-devel/gcc-13.0.1_p20230205/work/gcc-13-20230205/gcc/tree-ssa-loop-ivcanon.cc:1593 % gfortran-13 -O1 -fpeel-loops -funreachable-traps -c comment11.f90 during GIMPLE pass: cunroll comment11.f90:1:14: 1 | subroutine foo() | ^ internal compiler error: in check_loop_closed_ssa_def, at tree-ssa-loop-manip.cc:645 <identical backtrace follows> % gfortran-13 -v Using built-in specs.
