--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
@Kyril: Is it really failing for GCC 7.x ?

For me it works:

$ arm-suse-linux-gnueabi-g++-7 -v
gcc version 7.4.1 20190424 [gcc-7-branch revision 270538] (SUSE Linux) 

$ arm-suse-linux-gnueabi-g++-7 ~/Programming/testcases/pr91042.cc -c -O2
In function 'void store(P, T) [with T = __vector(4) unsigned int; P = int*]',
