Summary: GDB is unable to do inf-call of return type _Complex
on x86_64-linux
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
AssignedTo: unassigned@sourceware.org

test case
Test case is attached. Here are the steps to reproduce it.
$ gcc -g complex-ret.c -o complex-ret
$ ./gdb complex-ret
(gdb) b main
Breakpoint 1 at 0x40044c: file /scratch/yao/complex-ret.c, line 9.
(gdb) run
Breakpoint 1, main () at /scratch/yao/complex-ret.c:9
9 return 0;
(gdb) p return_float_complex (fc)
During symbol reading, incomplete CFI data; unspecified registers (e.g., rax)
at 0x40044c.
$1 = 0 + 0 * I // <-- return value is wrong.
(gdb) p return_double_complex (dc)
$2 = 0 + 0 * I // <-- return value is wrong.
(gdb) p return_long_double_complex (ldc)
../../src/gdb/amd64-tdep.c:622: internal-error: amd64_return_value: Assertion
`len <= 16' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
