re PR tree-optimization/50622 (ICE: verify_gimple failed for std::complex<double>) 

2011-12-02  Martin Jambor  <mjambor@suse.cz>

	PR tree-optimization/50622
	* tree-sra.c (load_assign_lhs_subreplacements): Force gimple operand
	if both lacc and racc are grp_partial_lhs.

	* testsuite/g++.dg/tree-ssa/pr50622.C: New test.
