 Subject: Re: lib/57756
 
 Additionally from the https://docs.oracle.com/cd/E19683-01/817-1983/6mhm6r4=
 es/index.html :
 "If an object contains both .init and .init_array sections, the .init secti=
 on is processed before the functions defined by the .init_array section for=
  that object."
 
 So we also have incorrect order of _init() and _initarray() inside crt0-com=
 mon.c. _init() has to be called before _initarray(); glibc does the same
