When compiled with -O3, smbtorture can crash after the following valgrind trace: ==16944== Conditional jump or move depends on uninitialised value(s) ==16944== at 0x57FFAC3: ndr_push_unique_ptr (ndr_basic.c:730) ==16944== by 0x58CB855: ndr_push_spoolss_SetPrinterInfo (ndr_spoolss.c:7939) ==16944== by 0x58E2F95: ndr_push_spoolss_SetPrinter (ndr_spoolss.c:24724) ==16944== by 0x417C78C: dcerpc_binding_handle_call_send (binding_handle.c:410) ==16944== by 0x417C986: dcerpc_binding_handle_call (binding_handle.c:547) ==16944== by 0x522059C: dcerpc_spoolss_SetPrinter_r (ndr_spoolss_c.c:1722) ==16944== by 0x2853BD: test_sd_set_level (spoolss.c:1248) ==16944== by 0x28F146: test_PrinterInfo_SD (spoolss.c:1962) ==16944== by 0x2A3C31: test_EnumPrinters_old (spoolss.c:6589) ==16944== by 0x41F6D66: internal_torture_run_test.part.0 (torture.c:442) ==16944== by 0x41F711F: torture_run_tcase_restricted (torture.c:758) ==16944== by 0x2018E8: run_matching.isra.1 (smbtorture.c:103) ==16944== by 0x20176B: run_matching.isra.1 (smbtorture.c:95) ==16944== by 0x20176B: run_matching.isra.1 (smbtorture.c:95) ==16944== by 0x201C12: torture_run_named_tests (smbtorture.c:143) ==16944== by 0x202F5B: main (smbtorture.c:661) My assumption is that with optimization gcc makes use of the fact that the structures that this patch moves go out of scope.
