c++ and global variables changed in functions - c++11

Question

I have these variable defined as global variables outside any function
//testing parameters (init to all nonfail)
int serverRandom = 0; //nonzero == fail > gotofail for first sha1 methode
SSLBuffer sigpar= 0; //nonzero == fail > gotofail for second sha1 methode
string hashOut = "nonfail"; //"fail" == error condition > gotofail for third sha1 methode
These variables are used in this function:
static OSStatus SSLVerifySignedServerKeyExchange(SSLContext *ctx, bool isRsa, SSLBuffer signedParams, uint8_t *signature, uint16_t signatureLen)
{
OSStatus err;
cout << "initval:"<< serverRandom<< signedParams<< hashOut<<endl;
if ((err = SSLHashSHA1::update(&hashCtx, &serverRandom)) != 0)
cout << "firstfail" <<endl;
goto fail;
if ((err = SSLHashSHA1::update(&hashCtx, &signedParams)) != 0)
cout <<"secondfail"<<endl;
goto fail;
//goto fail;
if ((err = SSLHashSHA1::final(&hashCtx, &hashOut)) != 0)
cout << "thirdfail" << endl;
goto fail;
cout << "nonfail" << endl;
fail:
SSLFreeBuffer(&signedHashes);
SSLFreeBuffer(&hashCtx);
return err;
}
Note that the global variables ServerRandom and hashout are accessed directly in that function while the sigpar variable is given to the signedParams arguments of the sslVerify function.
Now, I wrote a unit test to test each failing case seperatly via this function
void unittest(){
//all tests passing
cout << "-------------nonfail-------------" << endl;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
//first test fail
cout << "-------------firstfail-------------" << endl;
serverRandom = 1;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
serverRandom = 0;
//second test fail
cout << "-------------secondfail-------------" << endl;
sigpar= 1;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
sigpar= 0;
//third test fail
cout << "-------------thirdfail-------------" << endl;
hashOut = "fail";
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
hashOut = "nonfail";
}
Now it works perfectly for the first fail case eg. outputting the firstfail line. After that It does not work anymore as it just outputs the ---------secondfail-------- & ------thirdfail------- without outputting the failchecks (secondfail/thirdfail).
note that the initval inside sslverify...() shows the correct values, however the update/final function after the first testcause show 0 as a value for the respective values they recieve.

Answer 1

well, it was easy to solve in the end:
in the SSLVerifySignedServerKeyExchange() I just forgot to add {} around the multi-line if's after I added the cout<< so it would always goto fail after the first if
