Linux jdk1.6.0_25 x64(64 位)中可能出现的回归
更新:
我正在尝试再次尝试,因为我真的很想解决这个问题。如果有人愿意帮助我解决问题,我将不胜感激。
查看我上面发布的原始回溯,您可以看到正在调用此类的析构函数,而我什至没有构造该类型的对象!我对此一无所知。
#5 0x000000000087f46b in ~EmptyNode (this=0x18f67110) at ../../../plug-ins/mon/ASTNode.h:143
如果我取消注释上面的代码(即插件),当未连接调试器时,它不再使我的应用程序崩溃。当连接调试器时,它的 SEG 错误......很奇怪。
程序收到信号SIGSEGV,分段错误。 [切换到线程0x7fffd3ffc700 (LWP 4659)] 0x00007ffff17ef44f 在?? () (gdb) BT 0# 0x00007ffff17ef44f 在 ?? () 1# 0x0000000000000000 在 ?? ()
以下是 JVM 崩溃生成的完整 hs_err_pid:http://pastebin.com/Law2yEBN。我真的很感激您的帮助。
所以我想知道 gdb 是否显示对
~EmptyNode
的调用?当我什至不实例化这种类型的对象时。事实上我对此非常确定。为什么问题出现在我们的应用程序的 64 位版本中,而不是 32 位版本中...
我尝试启用 STL 调试宏,看看它们是否能帮助我找到这个问题的原因,但没有。这些宏是:-D_GLIBCXX_DEBUG -D_GLIBCXX_DEBUG_PEDATIC
。
原始问题:
我认为我在 Sun JVM 中看到了可能的回归,但在我向 Sun 提交错误报告之前我需要额外的确认。
- 之前在 jdk1.6.0_21 x64(64 位)上运行的代码现在在 jdk1.6.0_24+ 上崩溃,请参阅下面的日志。注意:如果我在 32 位中运行相同版本的 JVM,它不会崩溃。
我启用了以下开关。还有其他被证明有用的吗?
-verbose:jni
-Xcheck:jni
下面的日志是创建 JVM 后发生的情况。我还包含了崩溃的堆栈跟踪。其他线程是由 JVM 创建的,因为我的应用程序是单线程的。
- 您可以向我提供任何调试技巧吗?
我感谢所有的帮助,因为我一整天都在尝试解决这个问题,但我已经没有想法了。

Update:
I'm trying to have another shot at this because I'd really like to fix this problem. If anyone would like to aid me in solving the problem I'd greatly appreciate it.
Looking at the original backtrace I posted above, you can see that the destructor for this class is being called whilst I don't even construct an object of that type! I'm pretty clueless about this.
#5 0x000000000087f46b in ~EmptyNode (this=0x18f67110) at ../../../plug-ins/mon/ASTNode.h:143
If I uncomment the above piece of code (i.e., the plug-in), it no longer crashes my application when the debugger isn't attached. When the debugger is attached it SEG faults ... weird.
Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fffd3ffc700 (LWP 4659)] 0x00007ffff17ef44f in ?? () (gdb) bt 0# 0x00007ffff17ef44f in ?? () 1# 0x0000000000000000 in ?? ()
Here is the entire hs_err_pid that the JVM crash generates: http://pastebin.com/Law2yEBN. I really would appreciate the help.
So I'm wondering the gdb is showing a call to
~EmptyNode
? When I don't even instantiate an object of this type. I'm very sure of this in-fact.Why is the problem manifest in a 64-bit of our app and not a 32-bit version ...
I've tried enabling the STL debug macros to see if they would help me in trying to find the cause of this problem but it didn't. The macros are: -D_GLIBCXX_DEBUG -D_GLIBCXX_DEBUG_PEDANTIC
.
Original Question:
I think I'm seeing a possible regression in the Sun JVM, but before I go file a bug report with Sun I'd like extra confirmation.
- Code that was previously working with jdk1.6.0_21 x64 (64-bit) is now crashing with jdk1.6.0_24+, please see the log below. Note: If I run the same version JVM in 32-bit it does not crash.
I have the following switches enabled. Are there any more that would prove to be useful?
-verbose:jni
-Xcheck:jni
The log below is what happens after the JVM has been created. I've also included the stack trace of the crash. The others threads are created by the JVM because my app is single-threaded.
- Are there any debugging tips you could offer me?
I appreciate all the help as I've been trying to fix this all day and I'm running out of ideas.
