This one looks similar to the rest_of_handle_ree() issue: ==23637== Invalid write of size 8 ==23637== at 0xCF9951: rest_of_handle_dse() (dse.c:2874) ==23637== by 0x826B2A: execute_one_pass(opt_pass*) (passes.c:2327) ==23637== by 0x826FA4: execute_pass_list(opt_pass*) (passes.c:2387) ==23637== by 0x826FB6: execute_pass_list(opt_pass*) (passes.c:2388) ==23637== by 0x5EC801: expand_function(cgraph_node*) (cgraphunit.c:1641) ==23637== by 0x5EE5C6: compile() (cgraphunit.c:1745) ==23637== by 0x5EEC69: finalize_compilation_unit() (cgraphunit.c:2120) ==23637== by 0x4D52EB: c_write_global_declarations() (c-decl.c:10120) ==23637== by 0x8C845C: compile_file() (toplev.c:559) ==23637== by 0x8CA319: toplev_main(int, char**) (toplev.c:1881) ==23637== by 0x4ECD894: (below main) (libc-start.c:258) ==23637== Address 0x69fdd50 is 112 bytes inside a block of size 11,208 alloc'd ==23637== at 0x4028ECB: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==23637== by 0xDFAB97: xmalloc (xmalloc.c:147) ==23637== by 0x57E6C8: pool_alloc(alloc_pool_def*) (alloc-pool.c:282) ==23637== by 0xCF8F1C: record_store(rtx_def*, bb_info*) (dse.c:1544) ==23637== by 0xCF9D14: rest_of_handle_dse() (dse.c:2676) ==23637== by 0x826B2A: execute_one_pass(opt_pass*) (passes.c:2327) ==23637== by 0x826FA4: execute_pass_list(opt_pass*) (passes.c:2387) ==23637== by 0x826FB6: execute_pass_list(opt_pass*) (passes.c:2388) ==23637== by 0x5EC801: expand_function(cgraph_node*) (cgraphunit.c:1641) ==23637== by 0x5EE5C6: compile() (cgraphunit.c:1745) ==23637== by 0x5EEC69: finalize_compilation_unit() (cgraphunit.c:2120) ==23637== by 0x4D52EB: c_write_global_declarations() (c-decl.c:10120) ==23637==
