HarmonyOS 鸿蒙Next 更新到DP2后，在多线程中测量文本宽度出现问题

HarmonyOS 鸿蒙Next 更新到DP2后，在多线程中测量文本宽度出现问题 昨天手机更新到DP2后发现页面经常crash，排查后发现在子线程执行

import measure from '@ohos.measure'
import taskpool from '@ohos.taskpool'

@Concurrent
function multiMeasure(){
  let data:number[] = []
  for (let i = 0; i < 2000; i++) {
    let charWidth = measure.measureText({
      textContent: '我',
      fontSize: 80 + 'px'
    }) * 3
    data.push(charWidth)
  }
  return data;
}

async function asyncMultiMeasure(){
  let task:taskpool.Task = new taskpool.Task(multiMeasure)
  let data:number[] = [];
  data = await taskpool.execute(task) as number[]
  return data;
}


@Component
export struct measureTest{
  @State data:number[] = [0]

  async aboutToAppear(){
   this.data = await asyncMultiMeasure();
    console.log(`MEA-MSG: len:${this.data.length}`)
    this.data.forEach(d => {
      console.log(`MEA-MSG: num:${d}`)
    })
  }

  build() {
    Column(){
      Text(this.data[0].toString())
        .fontSize(20)

    }
  }
}

这是更新后的bug吗？

下面是一个实例代码

import measure from '@ohos.measure'
import taskpool from '@ohos.taskpool'

@Concurrent
function multiMeasure(){
  let data:number[] = []
  for (let i = 0; i < 2000; i++) {
    let charWidth = measure.measureText({
      textContent: '我',
      fontSize: 80 + 'px'
    }) * 3
    data.push(charWidth)
  }
  return data;
}

async function asyncMultiMeasure(){
  let task:taskpool.Task = new taskpool.Task(multiMeasure)
  let data:number[] = [];
  data = await taskpool.execute(task) as number[]
  return data;
}


@Component
export struct measureTest{
  @State data:number[] = [0]

  async aboutToAppear(){
   this.data = await asyncMultiMeasure();
    console.log(`MEA-MSG: len:${this.data.length}`)
    this.data.forEach(d => {
      console.log(`MEA-MSG: num:${d}`)
    })
  }

  build() {
    Column(){
      Text(this.data[0].toString())
        .fontSize(20)

    }
  }
}

Reason: Signal: SIGSEGV(SEGV_MAPERR)@0x0000000000000028 probably caused by NULL pointer dereference
