I’ve just started experiencing EXC_BAD_ACCESS (SIGBUS) crashes when attempting to start Evernote or Komodo Edit and  a minute after starting Chrome.
I had no idea what was causing this and looking on Google indicated everything from faulty memory to needing to re-install Mountain Lion.
However, it was only when looking for this error along with Evernote that I stumbled across something less radical that, thankfully, fixed the issue.
First launch Terminal.
Now run..
sudo update_dyld_shared_cache -force
Finally, reboot.
