Still in trunk:

../../gcc-150221/gcc/cse.c:2204:34: runtime error: signed integer overflow: 1 -

I confirm it is still in trunk 270309, must be compiled with 
nonzero optimization

~/local/gcc-270309-undefined/bin/gcc -S -O gccerr67.c
../../gcc/gcc/cse.c:2215:34: runtime error: signed integer overflow: 1 -
-9223372036854775807 cannot be represented in type 'long int'

Bug now moved at line 2215

offset = (get_integer_term (x) - get_integer_term (p->exp));
