re PR fortran/32432 (SEGV/endless loop after: "ERROR: ... already is initialized")
2007-07-03 Jerry DeLisle <jvdelisle@gcc.gnu.org>
PR fortran/32432
* gfortran.h: Change type of gfc_assign_data_value from void to try.
* data.c (gfc_assign_data_value): Return FAILURE if error found.
* resolve.c (check_data_variable): If gfc_assign_data_value returns
failure, break out of loop and return failure.
