The previous patch used snprintf to set the message string. The message string is not a formatted string and the snprintf will interpret '%' related characters as format specifiers when there are no associated output variables. A segfault ensues. This change replaces snprintf with a fortran string copy function and null terminates the message string. PR libfortran/105456 libgfortran/ChangeLog: * io/list_read.c (list_formatted_read_scalar): Use fstrcpy from libgfortran/runtime/string.c to replace snprintf. (nml_read_obj): Likewise. * io/transfer.c (unformatted_read): Likewise. (unformatted_write): Likewise. (formatted_transfer_scalar_read): Likewise. (formatted_transfer_scalar_write): Likewise. * io/write.c (list_formatted_write_scalar): Likewise. (nml_write_obj): Likewise. gcc/testsuite/ChangeLog: * gfortran.dg/pr105456.f90: Revise using '%' characters in users error message. |
