re PR middle-end/43390 (ICE: integral result type precision does not match field size of BIT_FIELD_REF)
2010-03-22 Richard Guenther <rguenther@suse.de>
PR tree-optimization/43390
* tree-vect-stmts.c (get_vectype_for_scalar_type): Make
sure vector extracts are type correct.
* gfortran.fortran-torture/execute/pr43390.f90: New testcase.
