A segmentation fault (often shortened to segfault) is a particular error condition that can occur during the operation of computer software. A segmentation fault occurs when a program attempts to access a memory location that it is not allowed to access, or attempts to access a memory location in a way that is not allowed (for example, attempting to write to a read-only location, or to overwrite part of the operating system).”
I have seen hundreds and hundreds of seg faults 😉 while coding for record module of LDTP and Spider SMS. But the one i saw yesterday was new, strange and fascinating. I am not sure whether i will be able to reproduce it again. The screenshot says why it is strange and fascinating 🙂 .
