Comment (by bonefish):
The three cases do use the same exit code:
{{{
318 8c2: 83 7d e4 05 cmpl $0x5,-0x1c(%ebp)
319 8c6: 75 0c jne 8d4 <_Z1av+0x3c>
320 8c8: be 03 00 00 00 mov $0x3,%esi

}}}
It's really just for the destruction of `myA` and the epilogue, though:
{{{
334 903: 83 ec 0c sub $0xc,%esp
335 906: 8d 45 dc lea -0x24(%ebp),%eax
336 909: 50 push %eax
337 90a: e8 51 fd ff ff call 660 <_ZN1AD1Ev@plt>
338 90f: 83 c4 10 add $0x10,%esp
339 912: 83 ff 01 cmp $0x1,%edi
340 915: 75 05 jne 91c <_Z1av+0x84>
341 917: be 11 00 00 00 mov $0x11,%esi
342 91c: 89 f0 mov %esi,%eax
343 91e: 8d 65 f4 lea -0xc(%ebp),%esp
344 921: 5b pop %ebx
345 922: 5e pop %esi
346 923: 5f pop %edi
347 924: 5d pop %ebp
348 925: c3 ret
}}}
I haven't checked how the addresses match up with the line number info.
