--- Comment #3 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
With glibc master I see:

$ ./testrun.sh ./p64
Phix hybrid interpreter/compiler.

Version 1.0.1 (64 bit Linux) Copyright Pete Lomax 2006..2016

Enter ? for options or filename to execute:

Is it the expected output?

However, running through execve the kernel shows the binary can not be loaded:

kernel: Code: ff ff 00 45 31 db 48 8d 15 c9 ac 00 00 4c 8d 05 46 8f 01 00 4c 8d
2d 1f 8f 01 00 49 89 c2 48 8d 58 ff 48 89 f8 49>
kernel: p64[54765]: segfault at 0 ip 00007fc7ce59c350 sp 00007fffd17839c0 error
4 in ld-linux-x86-64.so.2[7fc7ce57c000+2a000]

So I am not sure it is really a glibc error, the binary is also stripped and
not fully conformant (readelf -a show a lot of bogus information), so it is
really difficult to debug.  I think what might be happening is kernel ELF
binfmt is seeing some unexpected and thus throwing the error.
