This is really specific to the avr port, so you would need to talk with the
avr maintainer on these issues.
Apparently basic things such as support for long is not properly
supported by the avr back end, and this is turn causes bug box in gnat.

Denis,
would you please take a look in the avr back end?
Maybe its easy to support 'long' properly..
Thanks,
Bernd

I did the opposite and closed the other as a dup, since the orginal testcase
still fails with ICEs.

Bernd, Rolf,
Can you verify if this bug still exists? If so, I have in my notes that this
patch will fix this bug:
<http://svn.sourceforge.net/viewvc/avr-ada/trunk/patches/gcc-4.1-integer-bug-workaround.patch?view=log>
If so, can you attach the patch to this bug report?
Thanks

Yes, the problem is still present in 4.2
Bernd Trog developed a workaround available at

(sorry, I cannot attach it due to an internal error of bugzilla)

Fix support for long (or long long ?) in the avr back-end.

------- Comment #22 from linux at schildmann dot info 2007-12-17 19:53 -------
Hello,
when compiling the package
package Integer_Test is
type Int_Type is new Integer;
end Integer_Test;
the ICE occures when the GNAT node that represents
the lower bound of the integer type is converted
to the corresponding INTERGER_CST node.
In the above case comp_type (gcc/ada/cuintp.c:87)
represents a signed integer type with 16 bit precision
which is to small for the computations performed later:
The call to build_cst_from_int (Base = 32768) at
line gcc/ada/cuintp.c:110
gnu_base = build_cst_from_int (comp_type, Base);
returns an INTEGER_CST with the value -32768 which
causes an overflow (and later the ICE) in the call to
fold_build2 (MULT_EXPR, comp_type,
gnu_ret, gnu_base)
at line gcc/ada/cuintp.c:116.
See patch below.

Subject: Bug 10768
Author: charlet

* cuintp.c: Fix 16 bits issue for AVR.
On AVR, integer is 16 bits, so it can't be used to do math with
Base (=32768).
So use long_integer instead.
