抓住了非std异常 [英] caught non-std exception
问题描述
在FC4上用g ++使用STL和Posix线程
和套接字我正在捕获一个异常，即
不是std :: exception。知道它可能是什么？
可能是什么？我的捕捉宏的轮廓是
以下。
谢谢，
迈克。
#define MY_MACRO \
catch（MyExceptions& e）\
{\
... \\处理它们\
} \
catch（std :: exception& e）\
{\
... \\处理他们\
} \
catch（...）\
{ \
... \\这是什么\
}
On FC4 with g++ using STL and Posix threads
and sockets I am catching an exception that
is not a std::exception. Any idea what it
might be? An outline of my catch macro is
below.
Thanks,
Mike.
#define MY_MACRO \
catch (MyExceptions& e) \
{ \
... \\ process them \
} \
catch (std::exception& e) \
{ \
... \\ process them \
} \
catch (...) \
{ \
... \\ what is this \
}

我不知道，但有些系统会给你C ++风格
异常信号，如分段
违反除零。
我假设你排除了所有自定义异常
决定不从std :: exception派生出来？
尝试在gdb中运行程序，当它停止时
a backtrace with the quot; bt"命令并查看哪个
函数是在之前（及时），即
以下（在打印输出中），类似于
a" ;抛出。

I have no idea, but some systems give you C++-style
exceptions in the event of a signal, like a segmentation
violation of division by zero.
I assume you have ruled out all custom exceptions
that have decided not to derive from std::exception?
Try running the program in gdb, when it stops do
a backtrace with the "bt" command and see which
function is immediately before (in time), that is
below (in the printout), something that resembles
a "throw".

尝试在gdb中运行程序，当它停止时使用bt进行回溯。命令并查看之前（时间）的功能，即下面（在打印输出中），类似于抛出的东西。

很抱歉打扰你。我有：
throw（MyStuff）;
而不是：
抛出MyException（MyStuff）;
我对它编译感到惊讶。
Mike。
Sorry to trouble you with a typo. I had:
throw(MyStuff);
instead of:
throw MyException(MyStuff);
I am surprised that it compiled.

为什么？你几乎可以抛出一切。实际上，我想不到你不能扔的任何东西。

Why? You can throw pretty much everything. Actually, I cannot think
of anything you cannot throw.
