PR fortran/99205 - Out of memory with undefined character length
A character variable appearing as a data statement object cannot
be automatic, thus it shall have constant length.
gcc/fortran/ChangeLog:
PR fortran/99205
* data.c (gfc_assign_data_value): Reject non-constant character
length for lvalue.
* trans-array.c (gfc_conv_array_initializer): Restrict loop to
elements which are defined to avoid NULL pointer dereference.
gcc/testsuite/ChangeLog:
PR fortran/99205
* gfortran.dg/data_char_4.f90: New test.
* gfortran.dg/data_char_5.f90: New test.
