input file triggering the bug

Hi, there.
I got a segment fault when testing nm-new in binutils-2.30 with the command
`nm-new -a -C -l --synthetic poc`. 
The compilation flags used were "-g -O2".

The stack dumps given by valgrind are as follows:
Stack dump:
==10084== Invalid read of size 8
==10084==    at 0x403B55: print_symbol (nm.c:989)
==10084==    by 0x403F73: print_symbols (nm.c:1089)
==10084==    by 0x403F73: display_rel_file (nm.c:1205)
==10084==    by 0x4050D9: display_file (nm.c:1325)
==10084==    by 0x402FA9: main (nm.c:1799)
==10084==  Address 0x20 is not stack'd, malloc'd or (recently) free'd
