[CPMD-list] Crash when trying HF exchange

Dear CPMD experts,
in order to see how long computations including Hartree-Fock exchange really
take compared to non-hybrid density functionals I tried single-point calculations
on an isolated system (water molecule).
Using CPMD 3.7 on an IBM p690 or 3.7.2 on a Linux PC-cluster the job always
crashes when using the (not officially documented) keyword B3LYP or the
(officially documented) keyword HARTREE-FOCK. The coredump occurs during
the first do-loop in the subroutine HFXAA (file hfx.F, lines 223-226),
just at the beginning of the scf iterations.
This is the input I used:
! H2O

Did I make a mistake in my input?
Did anybody ever successfully run a B3LYP calculation? If so, under which
conditions?
Thank you. With best regards,
Christian Tuma.
