Hi,

I found the bug. IT seems to be a bad combination of Host-GCC and Target-GCC:

Host1-Environment:
GNU make version '3.81'
C compiler version '4.2.1'
C++ compiler version '4.2.1'

Target architecture = x86_64
Target GCC => 4.3.3
printf %f 7 => error => -26815615859...

----------------------------------

Host2-Environment:
GNU make version '3.81'
C compiler version '4.2.1'
C++ compiler version '4.2.1'

Target architecture = x86_64
Target GCC => 4.4.1
printf %f 7 => OK => 7.0000

-----------------------------------

Host3-Environment:
GNU make version '3.81'
C compiler version '4.3.2'
C++ compiler version '4.3.2'

Target architecture = x86_64
Target GCC => 4.3.3
printf %f 7 => OK => 7.0000
