Hi Ekaitz

Not that I am in any position to answer the question, but could you 
share a little bit more context?

Did the error occur when you were compiling gcc-4.7 or do programs 
compiled with this compiler have this issue?

What path led you to gcc-4.7? Can you share your compilation settings? etc..

Kind regards,

Reza
