Question

我在Android中有一个ndk-build项目，我想使用3.2中的Android Studio Profiler进行分析。但是我总是崩溃：

.wrapper {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.column {
  background: #e2e3e5;
  box-shadow: 0 2px 3px 0 rgba(0, 0, 0, 0.26);
  margin: 0 32px 14px 0;
  max-width: 250px;
  padding: 1rem;
}

@keyframes fadeInLeft {
  from {
    opacity: 0;
    -webkit-transform: translate3d(-20%, 0, 0);
    transform: translate3d(-20%, 0, 0);
  }
  to {
    opacity: 1;
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
  }
}
@keyframes fadeInTop {
  from {
    opacity: 0;
    -webkit-transform: translate3d(0, -20%, 0);
    transform: translate3d(0, -20%, 0);
  }
  to {
    opacity: 1;
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
  }
}
@keyframes fadeInRight {
  from {
    opacity: 0;
    -webkit-transform: translate3d(20%, 0, 0);
    transform: translate3d(20%, 0, 0);
  }
  to {
    opacity: 1;
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
  }
}

.first-column-start {
  -webkit-animation: fadeInLeft 0.8s;
  -moz-animation: fadeInLeft 0.8s;
  -ms-animation: fadeInLeft 0.8s;
  -o-animation: fadeInLeft 0.8s;
  animation: fadeInLeft 0.8s;
}

.second-column-start {
  -webkit-animation: fadeInTop 0.8s;
  -moz-animation: fadeInTop 0.8s;
  -ms-animation: fadeInTop 0.8s;
  -o-animation: fadeInTop 0.8s;
  animation: fadeInTop 0.8s;
}

.third-column-start {
  -webkit-animation: fadeInRight 0.8s;
  -moz-animation: fadeInRight 0.8s;
  -ms-animation: fadeInRight 0.8s;
  -o-animation: fadeInRight 0.8s;
  animation: fadeInRight 0.8s;
}

据我所知，2019-02-20 10:10:42.369 21888-21888/? A/DEBUG: pid: 21705, tid: 21882, name: engine >>> com.test.example <<< 2019-02-20 10:10:42.369 21888-21888/?

A/DEBUG: #05 pc 00182080 /data/data/com.test.example/libperfa_arm.so与C ++中的异常机制有关。但是如何解决这个问题？

我唯一尝试过的就是如果我在库中添加__gxx_personality_v0标志，那么此问题就可以解决。但是我想知道这里是否还有其他解决方案，因为-fno-exceptions与STL库不一致。

空指针取消引用__gxx_personality_v0
