Pasto - should have been:


$ gcc -w -fsanitize=float-cast-overflow new8.i

new8.i: In function ‘float2long’:
new8.i:11:23: internal compiler error: in gimplify_expr, at gimplify.c:8451
   *exponent = (int32 )log((double )value);
                       ^

gimple_statement_base**, bool (*)(tree_node*), int)
