Thanks.
Functions like
sys.posix.unistd: pipe, encrypt
sys.posix.stdlib: Xseed48, {e,j,n}rand48, lcong48
sys.posix.poll: poll
sys.posix.sys.time: utimes
sys.posix.sys.socket : socketpair
are currently affected in druntime (from 2.039).

In, 2.032 (just tested) it returns:
$ ./bug3604
input: 0 0
input.ptr: BFA00CB8
cast input: BFA00CB8
x = 0 0
x[0] = 0
x[1] = 0
ok
$
So not exactly what I written, but pipe is working.
So i tested it more precisly:
bug3604.d:
extern(C) int tttc(int[2] x);
void main() {
int[2] input;
tttc(input);
}
bug3604c.c:
#include stdio.h
int tttc(int x[2]) {
printf(just in C\n);
printf(x=%p\n, x);
printf(x[0]=%d\n, x[0]);
printf(x[1]=%d\n, x[1]);
printf(back from C\n);
}
# gcc -c bug3604c.c
# dmd2.032 bug3604.d bug3604c.o
# ./bug3604
just in C
x=0xbf988ff8
x[0]=0
x[1]=0
back from C
# dmd2.037 bug3604.d bug3604c.o
# ./bug3604
just in C
x=(nil)
Segmentation fault
#
So it is regression.
In `strace` for pipe example I see for 2.032:
pipe([3, 4])= 0
and for 2.037:
pipe(0) = -1 EFAULT (Bad address)
So it also passes NULL pointer (jiust like in tttc function) .
