Question

我在solaris 10中使用gsoap-2.8开发了一个ws客户端作为共享库。

如果从独立应用程序（可执行文件）调用ws客户端，它工作正常并且能够从服务器检索值。

(dbx) run data
Running: testws data
(process id 5998)
t@1 (l@1) stopped in getDataFromWS at 0xf8953fec
0xf8953fec: ExecuteMCEligibility       :        sethi    %hi(0x1e000), %g1
(dbx)cont
(dbx)execution completed, exit code is 0

如果同一个ws客户端从另一个共享库调用，它将崩溃并显示以下消息

t@12 (l@12) stopped in getDataFromWS at 0xf3ccc9e4
0xf3ccc9e4: getDataFromWS       :        sethi    %hi(0x1e000), %g1
Current function is writeData
180         retval = writeData(data);
(dbx) cont
      t@12 (l@12) signal SEGV (no mapping at the fault address) in soap_end_block at    
      0xf8ea42d8
      0xf8ea42d8: soap_end_block+0x0040:      ld       [%o0], %i3
      Current function is writeData
      180         retval = writeData(data);

(dbx) where
current thread: t@12

代码快照如下，

struct _ns2__getSomeData
{
    char *aaa;     
    char *bb; 
    char *cc;     
    char *dd;      
    char *ee;
    char *ff;  
    char *gg;       
    char *hh;      
    char *ii;     
};


struct _ns2__getSomeDataResponse
{
    char *xx;
    char *yy;  
};

int getDataFromWS( data )
{
    int status = sSUCCESS;
    soap mSoap;
    soap_init(&mSoap);
    mSoap.userid = mUserId;
    mSoap.passwd = mPassword;

    _ns2__getSomeData mcRequest;
    _ns2__getSomeDataResponse mcResponse;

    //initialize request and response  message values
    initRequestResponseMsgValues();

    // Calling external web serice using gSOAP interface
    int ret_val = ret_val = soap_call___ns1__getSomeData(&mSoap,
                                     (const char*) *(mCurrentHost),
                                     (const char*) mSoapAction,
                                     &mcRequest,
                                     &mcResponse );

    // Only return response if web service call was successfull
    if (ret_val == SOAP_OK )
    {
        //set values in data
    }

    soap_free_temp(&eligibleCheck.mSoap);
    soap_done(&eligibleCheck.mSoap);
    return status;
}

如果任何人可以提供有关如何解决此问题的提示，那将是一个很好的帮助。
