Server crash on alternatives.

[zaneenders]

The following API call triggers a crash in the server.

const FPCoreCrash1 = '(FPCore (c x y) (if (<= y (- 1.75e+15)) (* c (log1p (* (expm1 x) y))) (if (<= y 1.45e-16) (* (fma (fma (fma (* (pow (expm1 x) 3.0) c) 0.3333333333333333 (* (- 0.25) (* (* (pow (expm1 x) 4.0) y) c))) y (* (- 0.5) (* (pow (expm1 x) 2.0) c))) y (* c (expm1 x))) y) (* c (log1p (* (expm1 x) y))))))'
const crash_sample = await (await fetch(makeEndpoint("/api/sample"), {
  method: 'POST', body: JSON.stringify({
    formula: FPCoreCrash1,  seed: 475472373
  })
})).json()
const altBody = {
  method: 'POST', body: JSON.stringify({
    formula: FPCoreCrash1, sample: crash_sample.points
  })
}
const alternatives = await (await fetch(makeEndpoint("/api/alternatives"), altBody)).json()
