The line in rmm-diis.F where NSTRIP is set reads
NSTRIP=MIN(NSIM,WDES%NBANDS)*2
If W%OVER_BAND=.TRUE. and WDES%NBANDS<NSIM, this may result in a segmentation fault. It seems that the factor of 2 should not be there, or should only multiply NSIM. If LASYNC=.FALSE., then this bug will never surface.

Since the error surfaces only for LASYNC=.TRUE. the bug will not be fixed.
LASYNC is not really supported any longer (G. Kresse has updated the manual to say so). LASYNC=.TRUE. has not been tested for a long time, and errors have possibly creeped in at several places. In fact, the performance of LASYNC, was very disappointing and we finally gave up to use it...
