No, but if your GCC is configured --with-default-pie (it's enabled by almost
all Linux distros), during LTO gcc will be invoked with an explicit -pie in the
command line.

Without -flto, there's no explicit -fpie flag and the bug is not triggered by
the default PIE configuration alone.  So it appears triggered by -flto.
