the test case

## Write in front ,  i use afl to fuzz binutils2.40-nm-new , and then find this
bug.

## command : nm-new -C file

this test case , may make nm-new hang for much time until the system kill it ,
i have test it in ubuntu20.04 (compiler gcc 7.50 and gcc 9.4). 

it seems like a infinite loop  , i use gdb to debug it , it behaves like
infinite loop/
