--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Harald Anlauf <anl...@gcc.gnu.org>: https://gcc.gnu.org/g:ba013672f723f87f0c3b0c685dda5b3b2f1b3f3a commit r11-8357-gba013672f723f87f0c3b0c685dda5b3b2f1b3f3a Author: Harald Anlauf <anl...@gmx.de> Date: Wed May 5 15:25:50 2021 +0200 PR fortran/100274 - ICE in gfc_conv_procedure_call, at fortran/trans-expr.c:6131 When the check for the length of formal and actual character arguments found a mismatch and emitted a warning, it would skip further checks like that could lead to errors. Fix that by continuing the checking. Also catch a NULL pointer dereference. gcc/fortran/ChangeLog: PR fortran/100274 * interface.c (gfc_compare_actual_formal): Continue checks after emitting warning for argument length mismatch. * trans-expr.c (gfc_conv_procedure_call): Check for NULL pointer dereference. gcc/testsuite/ChangeLog: PR fortran/100274 * gfortran.dg/argument_checking_25.f90: New test. (cherry picked from commit a8b79cc939d6786293f654c42a2d1b0ab040de0e)
