Bug ID: 69589 Summary: [6 Regression] ICE in initialize_node_lattices, at ipa-cp.c:971 Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ipa Assignee: unassigned at gcc dot gnu.org Reporter: marxin at gcc dot gnu.org Target Milestone: --- Hello. Following ICE comes from Firefox test-suite, I was able to reduce the number of pre-processed source files to 3 to expose the internal compiler error. $ c++ -flto -O2 -rdynamic Unified_cpp_js_src*.ii lto1: internal compiler error: in initialize_node_lattices, at ipa-cp.c:971 0x113c6c8 initialize_node_lattices ../../gcc/ipa-cp.c:971 0x113c6c8 ipcp_propagate_stage ../../gcc/ipa-cp.c:2927 0x113da3c ipcp_driver ../../gcc/ipa-cp.c:4606 0x113da3c execute ../../gcc/ipa-cp.c:4698 Source files: https://drive.google.com/file/d/0B0pisUJ80pO1SWtLUnNVQkZwZFU/view?usp=sharing I tried to reduce it with creduce (now having capability to reduce multiple files), but it does not process any simplification. Thanks, Martin
