Example code crashes on linux

[Trzyipolkostkicukru]

Example code from README.md crashes on linux. The message I'm getting after installing swift-backtrace is
"Swift runtime failure: Double value cannot be converted to Int because it is either infinite or NaN"

Project files without the ".build" directory ThisIsBenchmark.zip (if I included .build it would be too big for github)

Information

• Package version: main branch
• Platform version: Ubuntu 20.04.2 LTS running in a VM
• Swift version: Swift version 5.5-dev (LLVM 8c37fc45eae308f, Swift 63b62320eb022d8) Target: x86_64-unknown-linux-gnu

Checklist

• If possible, I've reproduced the issue using the main branch of this package.
• I've searched for existing GitHub issues.

Steps to Reproduce

Replace this paragraph with an explanation of how to reproduce the incorrect behavior.
Include a simple code example, if possible.

• create new executable package
• add swift-collections-benchmark dependency
• copy-paste example benchmarks from README.md to main.swift
• optionally add swift-backtrace to show more info on crash
• run swift run -c release ThisIsBenchmark run out in terminal

Expected behavior

package is compiled, and example benchmark is executed

Actual behavior

package is compiled with a "remark: Incremental compilation has been disabled: it is not compatible with whole module optimization", but crashes at runtime. Without the backtrace package the error doesn't say anything, but with the backtrace package it looks like this:

Running 2 tasks on 76 sizes from 1 to 1M:
  Array<Int> sorted
  Set<Int> contains
Output file: /home/cukier/Desktop/ThisIsBenchmark/out
Appending to existing data (if any) for these tasks/sizes.

Also reproduced on macOS: apple/swift-collections#345 (comment)

This can happen when the average duration measured happens to be zero. The fix ought to be straightforward.
