solve() bug


Hi,

solve(x=a,b,deriv(f(x)))

results in SEGV for real-valued function f and any real values a and b

I can see the confusion between formal variable x and numeric
variable x.

An obvious work-around is to do 

g(x)=deriv(f(x))
solve(x=a,b,g(x))

I was wondering if I can achieve the same without defining an
intermediate function g.

Thanks

Igor
