re PR tree-optimization/55260 (ICE: in ipa_get_parm_lattices, at ipa-cp.c:263 with -O2 -fno-inline -fipa-cp-clone)

2012-11-20  Martin Jambor  <mjambor@suse.cz>

	PR tree-optimization/55260
	* ipa-cp.c (find_aggregate_values_for_callers_subset): Rename info to
	dest_info, use caller_info instead of info when determining whether
	callee is a clone.

	* testsuite/g++.dg/torture/pr55260-1.C: New test.
