libc Fatal signal 11 SIGSEGV

The error message "Fatal signal 11 (SIGSEGV)" indicates that the program has crashed due to a segmentation fault, which occurs when the program tries to access a memory location that it is not allowed to access. This can happen for a variety of reasons, such as dereferencing a null pointer, accessing an array beyond its bounds, or using a dangling pointer.

To fix this error, you need to identify the root cause of the segmentation fault and fix the underlying issue. One way to do this is to use a debugger, such as GDB, to step through the program and identify where the crash occurs. Once you have identified the problematic code, you can modify it to avoid the segmentation fault.

It is also important to ensure that your program is properly allocating and freeing memory, and that you are not accessing memory that has already been freed or that has not been initialized. This can help prevent segmentation faults from occurring in the first place
