With gdb I get:

(gdb) step
std::pair<long const, Service>::pair (this=) at /usr/include/c++/6/bits/stl_pair.h:288
288 constexpr pair(const pair&) = default;
(gdb) step

Program received signal SIGSEGV, Segmentation fault.
0x000055555566f3a8 in std::pair<long const, Service>::pair (this=) at /usr/include/c++/6/bits/stl_pair.h:288
288 constexpr pair(const pair&) = default;
(gdb) step
ASAN:DEADLYSIGNAL

Also can't get code text and number of string in trace. ASAN_SYMBOLIZER_PATH is set, ASAN_OPTIONS=symbolize=1 is also set, gcc option -g is set.
Function on step 0 in sanitizer code. Have no problem without sanitizer.
Please help me with this problems.

i met these error many times, i do not know if it is false positive。 because if i do not use Asan， my program is ok。
