Yes, I saw the bug report in Debian, and I did some tests, but I am
also puzzled about this bug.

The problem only appears on amd64 architectures. Unfortunately I don't
have access to an amd64 machine.

However, I think that there are two workarounds that can be tried out
here:

  - The first one is building the package without running the tests (I
    think that problem appears only when running the tests). I am not
    sure if this could be a Debian policy violation or not (I guess
    not).

  - The other one is trying to recompile gmp with -fexceptions and
    then ppl again to see if the problem persists. For details, see 
    http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=552959#25

Interestingly, this problem does not always appear:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=552959#35

That is someone reporting that the package built successfully on
amd64.

So weird thing.
