[英]0xC0000005: Access violation reading location 0xffffffffffffffff
I have: 我有:
I am seeing this crash occur only in Release and not debug. 我看到此崩溃仅发生在Release中,而不发生在调试中。 The crash also does not occur on neither debug or release when the unmanaged C++ app is run by itself. 当非托管C ++应用程序本身运行时,在调试或发布时也不会发生崩溃。
All I can say is the crash occurs in this line of code: 我只能说崩溃发生在以下代码行中:
if ((std::find(vstrEEDRRMachines.begin(), vstrEEDRRMachines.end(), m_sFrame.strSourceAddress) != vstrEEDRRMachines.end()
&& std::find(vstrEEDRRMachines.begin(), vstrEEDRRMachines.end(), m_sFrame.strDestAddress) != vstrEEDRRMachines.end())
|| (std::find(vstrRRRHMachines.begin(), vstrRRRHMachines.end(), m_sFrame.strSourceAddress) != vstrRRRHMachines.end()
&& std::find(vstrRRRHMachines.begin(), vstrRRRHMachines.end(), m_sFrame.strDestAddress) != vstrRRRHMachines.end()))
{
// Create appropriate buffer size for raw message (i.e. size of payload along with the extra padding
// for decoding)
m_sFrame.iMessageSize = m_sFrame.iPayloadLength;
m_sFrame.iOriginalMessageSize = m_sFrame.iPayloadLength;
m_sFrame.pszMessage = new unsigned char[m_sFrame.iPayloadLength + Constants::RSSL_DECODE_PADDING];
m_sFrame.pszOriginalMessage = new unsigned char[m_sFrame.iPayloadLength + Constants::RSSL_DECODE_PADDING];
}
Although I can't see what's inside vstrEEDRRMachines and vstrRRRHMachines (because we are in release), I can see when in the original C++/CLI wrapper that there are valid string entries in the vector. 尽管我看不到vstrEEDRRMachines和vstrRRRHMachines里面的内容(因为我们已经发布了),但是我可以看到在原始C ++ / CLI包装器中何时在向量中存在有效的字符串条目。

if (*_First == _Val) <-- CRASH OCCURS HERE
break;
return (_First);
}
I have no idea what's going on, since release mode with C# + C++/CLI + C++ apps is where the crash is occurring. 我不知道发生了什么,因为崩溃发生的地方是C#+ C ++ / CLI + C ++应用程序的发布模式。 Is there any way I can easily fix this? 有什么办法可以轻松解决此问题?
EDIT 编辑
It seems like this occurs 9 times out of 10, but i've noticed the times it does work, when I check the parameters of the Parse function just as it goes into the function (no lines are executed yet), all 3 vectors have normal values (the 1st one is 0, the second and third contain IP addresses as expected). 似乎这发生了10次中的9次,但是我注意到它确实起作用了,当我检查Parse函数的参数时,就像它进入函数一样(还没有执行任何行),所有3个向量都有正常值(第一个为0,第二个和第三个包含预期的IP地址)。 However, most of the time, as soon as we get into the Parse function, all 3 vectors have negative size and capacities... and when they are used, everything goes boom. 但是,大多数时候,一旦我们进入Parse函数,所有3个向量的大小和容量都为负...使用它们时,一切都会繁荣起来。 I'm going to past the entrance of the Parse function and also the C++/CLI wrapper before it. 我要经过Parse函数的入口以及它之前的C ++ / CLI包装器。

Don't know why I have received down votes for this, as the solution could be quite useful to people mixing C# and a C++/CLI wrapper. 不知道为什么我对此表示反对,因为该解决方案对于混合使用C#和C ++ / CLI包装器的人们可能非常有用。
I realized that the suspect line was actually this line: 我意识到可疑的行实际上是这一行:
//String^ managedStringTmp = managedString;
//std::string strInputFileNames = msclr::interop::marshal_as<std::string>(managedStringTmp);
std::string strInputFileNames = marshalString<E_UTF8>(managedString);
I've obviously changed it so that it is using this new "marshalString" function. 我显然已经对其进行了更改,以便它使用此新的“ marshalString”函数。 I used a marshal string template class from the link here, as it seems to address performance issues. 我使用了此处链接中的元帅字符串模板类,因为它似乎解决了性能问题。

Now all I need to do is figure out why returning true from the wrapper and assigning it to a boolean in C# returns false... but hopefully this will help some people out. 现在,我需要做的就是弄清楚为什么从包装器返回true并将其分配给C#中的布尔值会返回false……但是希望这会对某些人有所帮助。
UPDATE UPDATE
This explains why returning false or true in the wrapper back to C# won't work, and that we either need to use marshalling of the function (didn't want to do) or return 0 for false and 1 for true. 这解释了为什么在包装器中将false或true返回给C#将不起作用,并且我们要么需要使用函数的编组(不想做),要么为false返回0,为true返回1。
