--- Comment #13 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Thomas Koenig <[email protected]>: https://gcc.gnu.org/g:f2b1a0cae33adbd4942eb1ee966bb2d1f3768ffc commit r13-10333-gf2b1a0cae33adbd4942eb1ee966bb2d1f3768ffc Author: Thomas Koenig <[email protected]> Date: Tue May 19 14:09:35 2026 +0200 PR fortran/115260 - fix data corruption on inline packing/unpacking This patch fixes a data corruption occuring when a non-contiguous slice of an allocatable array component was passed to a procedure expecting a g77-style argument. The problem was the inline packing (PR fortran/88821) which went astray gfc_trans_scalar_assign was told to deallocate the argument upon return. The solution was to not pass that argument if passing a g77-style array, in effect a one-liner. This is a regression which goes back to all supported releases. gcc/fortran/ChangeLog: PR fortran/115260 * trans-expr.cc (gfc_conv_subref_array_arg): Pass false to dealloc argument of gfc_trans_scalar_assign if we are converting a g77-style argument. gcc/testsuite/ChangeLog: PR fortran/115260 * gfortran.dg/pr115260.f90: New test. (cherry picked from commit d81f2cb42b418484050599906f41978ed5005eaa)
