Strange, new testcase (with strdup) doesn't fail for me:

/home/max/install/master/bin/g++ -g -O0 -flto -fsanitize=address xptimer.cc
xptiming.cc test.cc -static-libasan
ASAN_OPTIONS=check_initialization_order=true ./a.out
max@max:~/test-lto/test-2/test$ ASAN_OPTIONS=check_initialization_order=true
./a.out
max@max:~/test-lto/test-2/test$ echo $?
