[Bug gas/11733] New: Out of bounds array access prevents build.

[forest dot belton at gmail dot com]

When compiling binutils for the sh4-elf target, the following error occurs:

../../src/binutils-2.20.1/gas/config/tc-sh.c: In function 'find_cooked_opcode':
../../src/binutils-2.20.1/gas/config/tc-sh.c:2540:7: error: array subscript is 
above array bounds

Upon closer inspection, it seems to be due to the line: name[nlen] = 0;

name is declared as a char[20], and the previous for loop describes name < 20 
as 
one of the predicates.

A fix for this would involve either changing name to be a char[21] instead, or 
perhaps changing the predicate in the loop to be name < (sizeof (name) - 1). 
I'm 
not familiar enough with the binutils source to comment on which would be the 
more suitable option.
