Catch 22 compiling ppl: Internal compiler error: Illegal instruction

Catch 22 compiling ppl: Internal compiler error: Illegal instruction

[Ángel González]

I am hitting an «internal compiler error: Illegal instruction» when
trying to compile ppl-0.11 on arm with gcc 4.1.3 (20080414).

This is almost surely fixed in newer GCC, the problem is that I was
building ppl precisely for compiling the latest gcc (4.7.2) [to overcome
a different gcc 'internal compiler error' bug].

So, what are my options now to get the non-bugged gcc?
Are you familiar with this error? Is there some easy workaround which
could be applied to ppl source code to bypass it?

Thanks

PPL is not required to build GCC, so just build GCC 4.7.2 without PPL.

Then, if you need a graphite-enabled GCC build PPL and rebuild GCC
using the 4.7.2 build you've just done.

Does it need a switch to disable graphite? (I don't see it on
./configure --help)

I currently get on gcc configure:

No, it isn't enabled unless you request it, or it's found in a standard
path.

You'll need to tell us the full configure command or noone can guess what's
happening.

The absence of PPL should not cause configure to fail unless you've done
something to cause it to be used.

It was a very simple configure line, mostly using --with-PACKAGE in
order to
point to the prefix folder.
So after, a few tests simplifying it, it turned out it was pulled by
--with-cloog
