Well, the common part is that all the crashes are inside JavaScriptCore
code, but we guess that this is due to the fact that it is the code that is
being executed when the stack gets corrupted (???). We are trying to find
some reference point in the code to make some debug but we have little
knowledge on it, specially the JavaScriptCore.

We have not done fully test in other platforms, but we are assuming that
this does not happen in the GTK/x86 port.
I'll try to post back a stack trace today,
