Comment:
Hello !
Could you allocate memory *after* raising an exception? Otherwise, those
exceptions trigger memory leaks.
`sig_on` and `sig_off` should always appear in pairs, but perhaps you
should use `sig_check` in this special case?

Can you check that the pointers you allocate are not 'null'?
