You can "safely" ignore this.  I believe it is because the generated 
file icache.c contains more than 0xffff lines (the file is ~80 000 lines 
long) and that is overflowing a 16-bit field used by stabs to store the 
line-number information.

You can also look at compiling that file with -gdwarf2 (from memory) 
which has better support for long files.
