我收到了这个奇怪的错误。只在linux上发生，我需要让它在那个操作系统上运行，但在windows上运行得很好。
仅发生在inFile.close();上。我们用大量的cout语句测试了这一点。
这是它在seg出错的函数。（Element300是一个c风格的字符串，有81个字符，包括终止符。此外，正在读取的文件是JAVA关键字，所以没有超过80个字符。）
以下是功能：
void HT300::fill300()
{
Element300 readLine = " ";
Element300 tempLine = " ";
int hashedValue;
int tempIndex = 0;
int tempProbed = 0;
int tempLineIndex = 0;
int readLineIndex = 0;
ifstream inFile;
inFile.open("RWJAVA.DAT");
if(!inFile)
{
cerr << "File not found: RWJAVA.DAT" << endl;
}
else
{
while(!inFile.getline(readLine,MAX_SIZE,'n').eof())
{
while(readLine[readLineIndex] == ' ')
{
readLineIndex++;
}
while(isalnum(readLine[readLineIndex]))
{
tempLine[tempLineIndex] = readLine[readLineIndex];
tempLineIndex++;
readLineIndex++;
}
tempLine[tempLineIndex] = ' ';
hashedValue = hash300(tempLine);
tempIndex = hashedValue;
while(strcmp(theTable[tempIndex].reserved,tempLine) != 0 && strcmp(theTable[tempIndex].reserved, " ") != 0)
{
tempProbed++;
tempIndex += 3;
if(tempIndex > MAX_TABLE)
{
tempIndex = 0;
}
}
if(strcmp(theTable[tempIndex].reserved," ") == 0)
{
strcpy(theTable[tempIndex].reserved,tempLine);
theTable[tempIndex].probed = tempProbed;
theTable[tempIndex].hashed = hashedValue;
}
tempIndex = 0;
tempProbed = 0;
tempLineIndex = 0;
readLineIndex = 0;
strcpy(tempLine, " ");
}
}
inFile.close();
return;
}
inWINDOWS上的文件错误：
Multiple errors reported.
1) Failed to execute MI command:
-var-create - * inFile
Error message from debugger back end:
-var-create: unable to create variable object
2) Failed to execute MI command:
-var-create - * inFile
Error message from debugger back end:
-var-create: unable to create variable object
3) Failed to execute MI command:

4) Failed to execute MI command:

5) Unable to create variable object
循环：
while(strcmp(theTable[tempIndex].reserved,tempLine) != 0 && strcmp(theTable[tempIndex].reserved, " ") != 0)
{
tempProbed++;
tempIndex += 3;
if(tempIndex > MAX_TABLE)
{
tempIndex = 0;
}
}
不知怎么就越界了。我通过更改选中的条件并将if语句设置为>=而不是>来解决此问题。
