Once in a while, booting an IBM POWER9 PowerNV system (8335-GTH) would generate

&_stext = 0xc000000000000000
&_end = 0xc0000000049d0000
i.e., it will cause static_obj() returns 1.

Does this mean that on POWER9 it can happen that a dynamically allocated
object has an address that falls between &_stext and &_end? Since I am
not familiar with POWER9 nor have access to such a system, can you
propose a patch?
