GDB Function arguments from assembly

Question

I'm trying to find out how stack pointer affects GDB ability to get the value of passed function arguments.

I created this deliberately broken c++ code:

int *wtf = 0;
extern "C" void noFrame(int a, int b, int c);
extern "C" {
    void frame(int a, int b, int c) {
        *wtf=7;
    }
}

int main(int argc, char *argv[])
{
    noFrame(1,2,3);
    return 0;
}

And assembly code

.code64
.text
.globl noFrame
.extern frame
noFrame:
    pushq %rbp
    movq %rsp, %rbp
    mov    %edi,-0x4(%rbp)
    mov    %esi,-0x8(%rbp)
    mov    %edx,-0xc(%rbp)
    callq frame
    popq %rbp
    ret

It was tailored to resemble the g++ generated one:

objdump -d ./program
...
00000000000007c0 <noFrame>:
 7c0:   55                      push   %rbp
 7c1:   48 89 e5                mov    %rsp,%rbp
 7c4:   89 7d fc                mov    %edi,-0x4(%rbp)
 7c7:   89 75 f8                mov    %esi,-0x8(%rbp)
 7ca:   89 55 f4                mov    %edx,-0xc(%rbp)
 7cd:   e8 02 00 00 00          callq  7d4 <frame>
 7d2:   5d                      pop    %rbp
 7d3:   c3                      retq   

00000000000007d4 <frame>:
 7d4:   55                      push   %rbp
 7d5:   48 89 e5                mov    %rsp,%rbp
 7d8:   89 7d fc                mov    %edi,-0x4(%rbp)
 7db:   89 75 f8                mov    %esi,-0x8(%rbp)
 7de:   89 55 f4                mov    %edx,-0xc(%rbp)
 7e1:   48 8b 05 58 08 20 00    mov    0x200858(%rip),%rax        # 201040 <wtf>
 7e8:   c7 00 07 00 00 00       movl   $0x7,(%rax)
 7ee:   90                      nop
 7ef:   5d                      pop    %rbp
 7f0:   c3                      retq  

You can see, both assembly code is very similar. But when I run it with gdb:

(gdb) run
Program received signal SIGSEGV, Segmentation fault.
0x00005555555547e8 in frame (a=1, b=2, c=3) at main.cpp:11
11          *wtf=7;
(gdb) bt
#0  0x00005555555547e8 in frame (a=1, b=2, c=3) at main.cpp:11
#1  0x00005555555547d2 in noFrame () at frame.s:24
#2  0x0000555555554814 in main (argc=1, argv=0x7fffffffe058) at main.cpp:18

You can see that GDB can find out function argument for frame, but not for noFrame, and idea why is it so?

I'm compiling code on AMD64 architecture and both g++ and as have -g switch enabled.
