At the moment, all we get is "pointer dereference failed".
We should also see the pointer value, and could enjoy even
more information.  The present tactic of setting context->last_error
to a static unchanged string would have to change.  An easy
improvement would be to statically allocate an new error_buffer
string field in the context, which embedded-C code could sprintf
into and incidentally use to set the context->last_error.
