1. A method for isolating errors in an embedded information handling system including a multi-threaded application having a signal handler, a shared library having at least one function, and a library encapsulation module having a function clone associated with up to each function of the shared library, the method comprising: (a) a first calling thread of the multi-threaded application calling a first function clone associated with a first function of the shared library; (b) the called first function clone determining a process ID associated with the first calling thread and a function ID associated with the called first function; (c) the called first function clone storing the process ID associated with the first calling thread and a function ID associated with the called first function to a library encapsulation table protected by a mutex; (d) the called first function clone calling the called first function; (e) the called first function generating an error; (f) the signal handler catching the error; (g) the signal handler determining the function ID and process ID associated with the error using the library encapsulation table; and (h) the signal handler writing the process ID and function ID associated with the error to a log file.
