re PR tree-optimization/55355 (internal compiler error: in tree_low_cst, at tree.c:6415)
2012-12-21 Martin Jambor <mjambor@suse.cz>
PR tree-optimization/55355
* tree-sra.c (type_internals_preclude_sra_p): Also check that
bit_position is small enough to fit a single HOST_WIDE_INT.
* testsuite/g++.dg/torture/pr55355.C: New test.
