------- Comment #24 from hjl dot tools at gmail dot com  2009-04-09 01:15 -------
Here is a testcase in C:

[hjl@gnu-6 pr39678]$ cat pr39678-2.c
struct Y { char c; };
struct X {
  struct Y y;
  __complex__ float val;
};

struct X __attribute__((noinline))
foo (float *p)
{
  struct X x;
  __real x.val = p[0];
  __imag x.val = p[1];
  return x;
}
void abort (void);
float a[2] = { 3., -2. };
int main()
{
  struct X x = foo(a);
  if (__real x.val != 3.)
    abort ();
  if (__imag x.val != -2.)
    abort ();
  return 0;
}
[hjl@gnu-6 pr39678]$ gcc pr39678-2.c  
[hjl@gnu-6 pr39678]$ ./a.out
Aborted
[hjl@gnu-6 pr39678]$
