	Segmentation Fault This means accessing memory at an illegal address. Probably accessing NULL pointer or some garbage-valued pointer. Can also happen when using free()/delete twice on the same memory location. Many times the exact location of the bug in your program is not where the program crashed. A bug can corrupt the memory, and the outcome will show only on the next access, that may be elsewhere. If it is not the trivial case of accessing a NULL pointer, you have to go through all the dynamic memory handling in your program. Bus Error Same as Segmentation Fault, only the memory violation was detected in another part of the OS. ld: fatal: entry point symbol `rrors' is undefined You compiled with "-pedantic -errors" instead of "-pedantic-errors". There is no space there. I try to link a mtm_ex1.o which is provided by the course staff and receive the following error: mtm_ex1.o: file not recognized: File format not recognized collect2: ld returned 1 exit status A. You probably use a wrong object, for example a Windows object on Linux or vice versa. It is also possible that you use a t2 object on a 32 bit Linux (t2 is 64 bit). You should link with the object file matching your Operating System Q. I try to link a mtm_ex1.o which is provided by the course staff and receive the following error: /usr/bin/ld: warning: i386 architecture of input file `mtm_ex1.o' is incompatible with i386:x86-64 output A. You probably use a wrong object - a Linux 32 bit object on t2 (t2 is 64 bit). You should link with the object file matching your Operating System
