Small C++ testcase
Debugging the following code works (on x86-64-linux) with GCC 4.8.3 20131205 -
or with GCC 4.9.0 20140211 and *without* -fsanitize=address.
Using ASAN, one has the following result. Namely, it is not possible to step
into the function "test()".
$ g++ -fsanitize=address -O0 -g test2.cxx
$ gdb ./a.out
...
(gdb) b main
Breakpoint 1 at 0x401131: file test2.cxx, line 15.
(gdb) run
Starting program: /data/local_users/tobiasb/xpcbool/unittests/a.out
Breakpoint 1, main () at test2.cxx:15
15 test();
(gdb) s
0: 1
1: 2
2: 3
[Inferior 1 (process 6022) exited normally]
