我看到我代码之外的Mono控制台应用程序中经常发生SIGABRT崩溃。
我搜索堆栈溢出，发现一个类似的问题（已满3年），被标记为已解决，但是我看到的是几乎相同的东西。这个问题是Intermittent SIGSEV (segfault), SIGABORT and process hangs in C# code using Mono。
环境：
Ubuntu 16.04.5 LTS
Linux 4.4.0-137-generic
X64 Architecture
我遇到以下错误：

Debug info from gdb:
=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=======================================================
Aborted
我不确定如何进行。
GetFromJson代码非常简单：
public static xfer GetFromJSON(string json)
{
return JsonConvert.DeserializeObject(json);
}
这是失败之前的300至400次呼叫。关联的库用在另一个控制台应用程序中，该应用程序无数次调用该应用程序。这两个应用程序之间的主要区别在于，一个没有事件的应用程序使用CPU执行计算，而一个有问题的应用程序使用通过OpenCL访问的NVidia GPU。
