No, this is not a gold bug on x86_64. ld.bfd may link without complaint, but
the resulting shared library will crash, I think. There are calls to
_ZN5QListI7QStringED1Ev which resolve to 0 (ie. the ELF header in the shared
lib).
This seems to be a fairly recent bug. On x86_64, 20141126 and 20141203
miscompile the unreduced testcase while 20141111 looks to be OK. You can
easily see whether there is a problme by running
nm *.o | grep _ZN5QListI7QStringED
0000000000000000 W _ZN5QListI7QStringED2Ev
0000000000000000 n _ZN5QListI7QStringED5Ev
0000000000000000 W _ZN5QListI7QStringED1Ev
0000000000000000 W _ZN5QListI7QStringED2Ev
0000000000000000 n _ZN5QListI7QStringED5Ev
If as above you see only one copy of _ZN5QListI7QStringED1Ev, then only one of
the two comdat groups define that symbol.
