constructors/destructors compiled twice

[Kövesdi György]

Hi,

I would like to use C++ for 8-bit AVR CPUs, so saving space would be 
important.
I found that the constructors and destructors always have two instances, which 
are exactly the same. I tried it for X86, X86/64, M68k, and AVR platforms, 
with the same result, so it is not platform-dependent.

Here is a disassembled example:

000000f8 <valami::valami()>:
  f8:   fc 01           movw    r30, r24
  fa:   84 e0           ldi r24, 0x04   ; 4
  fc:   91 e0           ldi r25, 0x01   ; 1
  fe:   91 83           std Z+1, r25    ; 0x01
 100:   80 83           st  Z, r24
 102:   13 82           std Z+3, r1 ; 0x03
 104:   12 82           std Z+2, r1 ; 0x02
 106:   08 95           ret

00000108 <valami::valami()>:
 108:   fc 01           movw    r30, r24
 10a:   84 e0           ldi r24, 0x04   ; 4
 10c:   91 e0           ldi r25, 0x01   ; 1
 10e:   91 83           std Z+1, r25    ; 0x01
 110:   80 83           st  Z, r24
 112:   13 82           std Z+3, r1 ; 0x03
 114:   12 82           std Z+2, r1 ; 0x02
 116:   08 95           ret

Is it possible to switch off this behavior?
