--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:eaf6cfabe542e8bd919495fb784e04d455fdd4c3 commit r15-10727-geaf6cfabe542e8bd919495fb784e04d455fdd4c3 Author: Richard Biener <[email protected]> Date: Thu Jan 22 13:12:43 2026 +0100 tree-optimization/123741 - fix segfault with BB vect and masked stores When vectorizing the body of an if-converted loop with BB vectorization we can end up vectorizing masked stores. But the code tracking whether a loop used masked stores failed to check we're doing loop vectorization. PR tree-optimization/123741 * tree-vect-stmts.cc (vectorizable_store): Add missing check on loop vectorization. * gfortran.dg/vect/vect-pr123741.f90: New testcase. (cherry picked from commit c7c5112fa19eeb01656e000c2b7732e86be8782e)
