>From the results printed by gdb and lldb above, it can be observed that after compiling the code with Clang, debugging with GDB proceeds without any issues, and the value of variable var298 is correctly output. However, when debugging with LLDB, the value of variable var298 cannot be retrieved.

Compilation command:
```clang++ test_case_0.cpp  -O3 -o -g -fno-inline```
