Detailed Description

Finds function calls where it is possible to cause a not null-terminated result.

Usually the proper length of a string is 'strlen(src) + 1' or equal length of this expression, because the null terminator needs an extra space. Without the null terminator it can result in undefined behaviour when the string is read.
