I may have found the problem or at least something close to it:

( and also:https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59463
but 59463 seems to have been fixed by gcc 4.9.1)
Try this simple test mentioned in bug 64364:
Create a file foo.cc with the single line:
#include<limits>
then try to compile foo.cc with g++:
g++ -c foo.cc
This will succeed in creating foo.o without error or warning
on a normal system (it worked for me). If it fails, note what
Mikael Pettersson posted in gcc bug 64364:
"Re-run g++ on the testcase with the -v flag, note the
command line for cc1plus, run cc1plus from gdb with that
command line, and show us the faulting instruction and
what code/function it occurs in."
The problem in bug 64364 may be caused by an incorrect CPU/arch
setting that happened while building gcc - or more specifically
with regard to its support libraries such as gmp.
Cheers,
Mike Shell
Your are right!
Doing the above test produced the same error.
package atk:/usr/src/atk> g++ -c -v foo.cc
