[PATCH] memcmp() error in gas/dwarf2dbg.c

[Hannes Reinecke]

Hi,

there is a possible memory overflow in gas/dwarf3dbg.c: get_filenum():375

	if (memcmp (filename, dirs[dir], dir_len) == 0
	    && dirs[dir][dir_len] == '\0')

dir_len is set to strlen(filename), which will overflow onto unallocated 
memory if strlen(filename) > strlen(dirs[dir]).
The attached patch fixes this.

Please keep me cc'ed as I'm not on this list.

Cheers,

Hannes
