--- Comment #5 from Uli Schlachter <psychon at znc.in> ---
Does anyone know why this bug actually occurs? I just got the command line that
is used for calling libtool via "make V=1", added "../boilerplate/.libs/*.o" at
the end, hit enter and everything linked fine.

So the problem is the static convenience library which we use for
boilerplate/cairo-boilerplate.la and somehow something cannot work with LTO and
static libraries. However, I can't find anything mentioning this online.

@yunlian:
In comment 1 you wrote: "It is because when linking some .so, the flag -flto is
not added."
What makes you think so? Can you provide more details? That doesn't seem to
match my findings.
