test case

inferior gets SEGV when gdb does inf-call of returning _Complex
{float|double|long double}.

$ gcc -marm -g ~/complex-ret.c -o complex-ret
$ ./gdb ./complex-ret
(gdb) b main
Breakpoint 1 at 0x8368: file /home/yao/complex-ret.c, line 9.
(gdb) run
Starting program: /home/yao/gdb/gdb-fsf-git/build/gdb/complex-ret

Breakpoint 1, main () at /home/yao/complex-ret.c:9

(gdb) p return_double_complex (dc)
During symbol reading, incomplete CFI data; unspecified registers (e.g., r0) at
0x8368.

Program received signal SIGSEGV, Segmentation fault.
0x000083d0 in return_double_complex (dc=4 + 1.146232298351692e-321 * I) at

21        return dc;
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on".
Evaluation of the expression containing the function
(return_double_complex) will be abandoned.
When the function is done executing, GDB will silently stop.
