Gamma-ray line emission is calculated for thermonuclear excitation of very-high-temperature (10 billion to 1 trillion K) ions which may exist in accreting matter around neutron stars and black holes. The 4.438-MeV line from deexcitation of the first excited nuclear state of C-12 should be the easiest to observe in both the continuous and transient emission spectra of such sources.
