Ruby中冻结的线程组异常

我使用嵌入式Ruby（Ruby版本1.8.6）从CPP调用Ruby代码。我将一个Ruby代码传递给rb_eval_string（），它将创建一个新线程。多次运行此cpp代码（大约20次）会导致内核转储SIGSEGV（信号11），stacktrace显示导致内核转储的原因是eval.c的rb_eval_string（）中引发了异常：

#5  <signal handler called>
#6  rb_longjmp (tag=6, mesg=365482760) at eval.c:4634
#7  0x00002aaaabd7fdc1 in rb_exc_raise (mesg=6) at eval.c:4650
#8  0x00002aaaabd89ae2 in eval (self=365613880, src=367575400, scope=4, file=0x15ad1f99 "(eval)", line=140)
at eval.c:6565
#9  0x00002aaaabd8a631 in rb_eval_string (str=0x2aaaac0bffe0 "<String containing ruby code which is passed to this function>"...)
at eval.c:1707

上述例外情况的原因是什么？应该做些什么来避免它

下面是我传递给rb_eval_string_protect（）的ruby代码：

“需要‘监视器’\n”
“需要“套接字”\n”
“包括RubyInterpreter\n”
“$rubyPort=11111；\n”

“如果（@mHashMap[key]！=nil）\n”
“elem=@mHashMap[key].pop（）；\n”
“如果（@mHashMap[key].length==0）\n”
“@mHashMap.delete（键）\n”
“结束\n”
“返回元素；\n”
“结束\n”
“结束\n”
“返回零\n”
“结束\n”
“结束\n”
“类MyThread<线程\n”

“超级（）\n”
“@owner=firstTask\n”
“结束\n”
“def getOwner（）\n”
“返回@owner\n”
“结束\n”
“结束\n”
“def embeddedLoop（）\n”
“keepRunning=false；\n”
“服务器=新闻服务器（）；\n”
“$isEmbeddedLoopReady=true；\n”
“如果（session=server.accept），则\n”
“keepRunning=true；\n”
“结束；\n”
“$runningTaskCount=0\n”
“while（keepRunning==true）\n”
“会话。读取（1）；\n”
“rubyTask=RubyInterpreter.getRubyTask（）\n”
“如果（rubyTask！=nil）\n”
“$runningTaskCount+=1\n”
“s=MyThread.new（rubyTask）{\n”
“开始\n”
“rubyTask.execute（）\n”
“$runningTaskCount-=1\n”
“营救标准错误\n”
“rubyTask.notifyCompletion（）\n”
“$runningTaskCount-=1\n”
“结束\n”
“}\n”
“否则\n”
“keepRunning=false\n”
“结束\n”
“结束\n”
“$hasEmbeddedLoopFinished=true\n”
“结束\n”
“$embeddedLoopThread=Thread.new{\n”
“开始\n”
“embeddedLoop（）\n”
“营救标准错误\n”
“放置\“****严重内部错误****\”\n”
“放置$！.backtrace.join（\“\\n\”）\n”
“结束\n”
“}\n”
“而（$isEmbeddedLoopReady==false）\n”
“结束\n”；

由于我正在从Ruby代码调用cpp方法RubyInterpreter.getRubyTask（），因此我定义了以下内容： sModule=rb_define_模块（“RubyInterpreter”）； rb_gc_寄存器_地址（&S模块）； rb_define_singleton_方法（sModule，“getRubyTask”，reinterpret_cast（RubyInterpreter:：getRubyTask），0）

getRubyTask（）返回一个简单的Ruby任务，例如puts'Hello！'

异常似乎是从eval.c的rb_thread_start_0（）抛出的

谢谢，
