我正在编译我的程序,clang++ -fsanitize=memory -fsanitize-memory-track-origins -fno-omit-frame-pointer -g -O0
当我运行它时,输出是:
matiu@matiu-laptop:~/projects/json++11/build$ ./tests

我怎样才能让它像美丽的例子一样显示行号:http: //clang.llvm.org/docs/MemorySanitizer.html
我怀疑这可能是不可能的,因为我的程序是一大堆嵌套的 lambda:https ://github.com/matiu2/json--11/blob/master/tests.cpp
