Compiler output, most probably. I cannot reproduce it. I tried:
struct xid_command
{
int syscall_no;
long int id[3];
volatile int cntr;
volatile int error; /* -1: no call yet, 0: success seen, >0: error
seen.
Some more analysis:
We enter libc from openssh code with the correct values in rsi and rdi:
(gdb) u
=> 0x56560e45 : call 0x5655d0b0
(gdb) info r
rax0xfffe 65534
rbx0x5663a000 1449369600
rcx0x0 0
rdx0x0
Package: libc6
Version: 2.31-1

This is related to #965086 and #965087 (and, in fact, possibly
causing them). After a glibc upgrade half the system services
(postfix, sshd, apt-get(!)) don’t work any more.
