What GMP are you using? I'm pretty sure I just built (on my home
machine, will check details tonight) with GMP on Mac OS X 10.4.6 with
the default gcc (I assume 4.0x), with no such problems. XEmacs
21.5.26 with one unrelated patch (already in CVS). I'm using the GMP
from DarwinPorts, updated April 5 or 6.
% port installed gmp
The following ports are currently installed:
gmp ＠4.1.4_2 (active)
I don't think the error is in gmp itself but in some part of the loadup
that is getting a value it does not expect as a result of bignum
support. I think the backtrace might lead to finding that place in the
code. On the G5 (iMac) the problem triggers when --enable-union-type
is configured in. On my older powerbook, removing that directive did
not fix the problems with the earlier version of gmp.
If I get time, I will try a compile on the G4 machine with the new gmp
version installed to see if --enable-union-type is the problem.
However, if it is, then does that mean that the real problem is an
alignment error that gets triggered when an object is referenced that is
not as it is expected? If so, could that point to something lower
level?
