--------------------------------

             Summary: Memory corruption happens consistently during the access of any CFURL
API's of CoreFoundation framework
                 Key: AMQCPP-522
                 URL: https://issues.apache.org/jira/browse/AMQCPP-522
             Project: ActiveMQ C++ Client
          Issue Type: Bug
          Components: Build Support, CMS Impl, Decaf
    Affects Versions: 3.8.0, 3.7.0, 3.6.0, 3.5.0
         Environment: Mac OS X - 10.8.5 (Mountain Lion) 

Application that uses CoreFoundation.framework (from Mac OS SDK 10.7) and activemq library
together.
            Reporter: Sahayaraj
            Assignee: Timothy Bish
            Priority: Blocker


Steps to recreate the issue.

Step 1 :- Download the activemq-cpp-library-3.8.1-src.tar file from activemq website.

Step 2 :- Build the library on Mac OS X 10.8.5 as per instructions given in ReadMe.txt file

Step 3 :- Build will be successful and you could get static and dynamic binaries.

Step 4:- Create a sample cmd-line application in XCode 4.4.1 and use the activemq static library
along with the usage of CoreFoundation.framework from Mac OS 10.7 SDK.

Step 5 :- Define the structure to createa linked list as follows

typedef struct myList {
 char name[128];
 struct myList *next;
} myListType;

void functiontocrash() {
myListType namelist[100] = {0};

        CFStringRef pathRef = CFSTR("MyLib:Apache:ActiveMQ:"); // it could be any folder path
in HFS notion.
        CFURLRef urlRef = CFURLCreateWithFileSystemPath(NULL, pathRef, 2, TRUE);

}

Step 6: Build the application. It would be successful.

Step 7: Run the application, then it crashes

You could get the following crash consistently

Thread 11 Crashed:

1   com.apple.CoreFoundation      	0x00007fff8ccebccb CFStringCreateWithBytes + 59
2   com.apple.CoreFoundation      	0x00007fff8ccf1a6c CFURLCreateFromFileSystemRepresentation
