This says that on line 355 of the file func2.cc you called some library 
function which crashed.  The first thing to check in these cases is the 
arguments passed to that library function: look for uninitialized 
pointers, out-of-bounds references to arrays, etc.

This says that the crash happened because you tried to access an illegal 
address.  This also suggests uninitialized pointers are the cause.
