Hi Bernd,

I read you reply better again... just to understand better.
Is the unwind-dw2-fde-glibc wrong/unusable for uclibc being strictly
based on some glibc features, or it's one of the possible
implementation ?
In case it's wrong/unusable, then should be worth add a patch to gcc
configuration into buildroot.


Thanks and regards,
Carmelo
