I'm sorry that the function in question is rather messy, but the problem is rather specific. I'm setting a constant 'c' and evaluating the local maximum of a function like so:

```
c = 1E6
find_local_maximum(lambda f: abs(1000*(2*pi*f*i)/(0.1*(2*pi*f*i)^2+1000*(2*pi*f*i)+c)), 1000, 3000)
```

In this case, I get the expected output. If I set `c = 1E7`

, or a nearby value, like `c = 1.123E7`

or `c = 3E7`

, I get the following error:

```
RuntimeError: ECL says: THROW: The catch MACSYMA-QUIT is undefined.
```

Now, if I set `c = 5E7`

or `c = 1E8`

, I get no error. It's also worth noting that `find_local_minimum`

with the exact same set of values and function does not have this same issue. Finally, the type of c is `sage.rings.real_mpfr.RealLiteral`

in each case.

What could be causing this problem? Is there a workaround or a potential bug fix?
