String merging is broken:

Breakpoint 1, gold::Input_file::try_extra_search_path (
    input_argument=input_argument@entry=0x757c98, filename="main.o",
    found_name=found_name@entry=0x879578, namep=namep@entry=0x7fffffff7110)
    at /export/gnu/import/git/binutils/gold/
975      if (*pindex > 0 || ::stat(name.c_str(), &dummy_stat) < 0)
(gdb) p name
$1 = "Group end without group start/main.o"
