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

Hi,

I'm digging on old compiler versions for bootstrapping purposes and I realized 
that gcc 4.7 and 4.8 packages don't compile on x64.

We have been able to reproduce the failure of gcc 4.7 but we didn't test the 
4.8 error that far.

In gcc-4.7 the error is the following:

./md-unwind-support.h:60:47: error: dereferencing pointer to incomplete type

I guess there's something missing there but I'm out of ideas to dig on this 
further.

Anyone?
