--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I can confirm GCC doesn't suggest l_24, but I'm not sure it's reasonable to
expect it to do so after so many parse errors.

If you fix the first two errors then you do get it:

91839.c:6:10: error: ‘l_2’ undeclared (first use in this function); did you
mean ‘l_24’?
    6 |   return l_2[0];      //error
      |          ^~~
      |          l_24


Your code is ill-formed. GCC tells you it's ill-formed. I don't see a bug here.
