Hi, all.

This simple invalide code makes GCC ICE.

Input:
//test.cc
extern "C" ""a

Command:
g++ test.cc

Output:
test.cc:1:12: error: unable to find string literal operator ‘operator""a’ with
‘const char [2]’, ‘long unsigned int’ arguments
    1 | extern "C" ""a
      |            ^~~

See <https://gcc.gnu.org/bugs/> for instructions.

I tested in GCC trunk 20200726, and it seems not to make GCC-10 or downwards 
versions crashed. 

Thanks,
Haoxin
