Child process terminated with signal 10: Bus error

When using a certain Regex and finding all matches of a String, and converting the Sequence to a List in an async couroutine, on iOS I end up with from the terminal:

Child process terminated with signal 10: Bus error

And the IDE looks really sad:

private val REGEX_IMAGE = Regex("<img[\\w='\":/.,{}&; -]* src=\\s*(['\"])((?:(?!\\1|\\\\).|\\\\.)*)\\1?.*>")

internal fun findImages(description: String): List<MatchResult> {
  return REGEX_IMAGE.findAll(description)
    .toList() // This causes a segmentation fault when used in conjunction with coroutines.
}

Note that when I either remove the toList() call or remove the async call, the regex works. However, both aren't an option for me.
