Description

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:
