Hello Guillaume,

Is the regression issue specific to Mac OS X with gcc 3.3? Or is this  
a known problem on all platforms with gcc 3.3? (Linux too? Intel and  
PPC?). I think it's important to have this fixed as compiling with  
gcc 3.3 on Mac OS X is the only way be compatible with all systems  
(10.2 -> 10.4).
