Bug in AxisEngineException with fix

[sharon liang <sh...@sbcglobal.net>]

Hi,

I am testing clients on Windows platform. The test1 crahed when it was 
not able to load a DLL. Here is the call stack:

_free_dbg_lk(void * 0x1006a36c `string', int 1) line 1044 + 48 bytes

KERNEL32! 7c59893d()


In int XMLParserFactory::loadLib(), when PLATFORM_LOADLIB() fails, it 
tries to do "throw 
AxisEngineException(SERVER_ENGINE_LOADING_PARSER_FAILED, PLATFORM_LOADLIB_ERROR);" 

The second parameter PLATFORM_LOADLIB_ERROR will be deleted in 
void AxisEngineException::processException(const int iExceptionCode, 
char* pcMessage)

However PLATFORM_LOADLIB_ERROR  was defined as empty string "" in   
src\platforms\windows\PlatformSpecificWindows.hpp. 

#define PLATFORM_LOADLIB_ERROR     ""

Therefore it crashed.

The fix will be define it as NULL:
#define PLATFORM_LOADLIB_ERROR     NULL

And change function void AxisEngineException::processException(const 
int iExceptionCode, char* pcMessage)

To
void AxisEngineException::processException(const int iExceptionCode, 
char* pcMessage)
{
AxisString sMessage ="";
if (pcMessage)
  AxisString sMessage = pcMessage;
    m_sMessage = getMessage(iExceptionCode) + " " + sMessage;
    if(pcMessage)
        delete pcMessage;
}

Let me if it make sense.

Thanks

David
