--- Comment #4 from Ilya Palachev <i.palachev at samsung dot com> --- > g++ test.o -o test -Wl,-flto > /tmp/ccEhycoY.ltrans0.ltrans.o:ccEhycoY.ltrans0.o:function > __static_initialization_and_destruction_0(int, int): error: undefined > reference to '__asan_before_dynamic_init' > /tmp/ccEhycoY.ltrans0.ltrans.o:ccEhycoY.ltrans0.o:function > __static_initialization_and_destruction_0(int, int): error: undefined > reference to '__asan_after_dynamic_init' > collect2: error: ld returned 1 exit status Such error is usual when option -fsanitize=address is not specified at the 2nd stage. For example, without option -flto gcc prints the following error: g++ -c test.cpp -fsanitize=address -o test_nolto.o g++ test_nolto.o -o test_nolto test_nolto.o:test.cpp:function main: error: undefined reference to '__asan_report_load4' test_nolto.o:test.cpp:function __static_initialization_and_destruction_0(int, int): error: undefined reference to '__asan_before_dynamic_init' test_nolto.o:test.cpp:function __static_initialization_and_destruction_0(int, int): error: undefined reference to '__asan_after_dynamic_init' test_nolto.o:test.cpp:function _GLOBAL__sub_D_00099_0_main: error: undefined reference to '__asan_unregister_globals' test_nolto.o:test.cpp:function _GLOBAL__sub_I_00099_1_main: error: undefined reference to '__asan_init_v4' test_nolto.o:test.cpp:function _GLOBAL__sub_I_00099_1_main: error: undefined reference to '__asan_register_globals' collect2: error: ld returned 1 exit status So it seems that above patch provides that gcc produces correct output.
