Both are possible. If you watched the cvs/svn commits over the last year 
or so, several asterisk issues have been identified and corrected 
relating to mem allocation, dereferencing, etc, etc.
I don't know that anyone has actually kept track of bugs vs versions to 
know which versions might be suspect, but it might help if you'd include 
  which distro/kernel you're running, asterisk version, types of cards 
installed, etc.
You might also try running memtest just to rule out memory failures or 
issues.
