[Bug tree-optimization/23173] New: ICE: tree check: expected real_cst, have integer_cst in const_binop, at fold-const.c:1512

["micis at gmx dot de" <gcc-bugzilla@gcc.gnu.org>]

When I compile gsl1.5 using the options -O2 -ffast-math -ftree-vectorize with 
the actual snapshot of gcc41 (20050730) I get an ICE.

last working snapshot is  gcc-4.1-20050604
first failing snapshot is gcc-4.1-20050611


gcc41i -O2 -ffast-math -ftree-vectorize -c coulomb.i -o coulomb.o
coulomb.c: In function 'coulomb_F_recur':
coulomb.c:525: internal compiler error: tree check: expected real_cst, have 
integer_cst in const_binop, at fold-const.c:1512
