[交流] 【求助】Segmentation fault when running a “Geometric optimization” job

Hi all,

I get a "Segmentation fault" error when I running a  “Geometric
optimization” job under OpenMPI. MPI said "mpiexec noticed that job rank 3
with PID 3248 on node localhost.localdomain exited on signal 11 (Segmentation
fault)."

The end of the log file is pasted bellow:

At SCF step   20, etot is converged :
for the second time, diff in etot=  1.453E-07 < toldfe=  1.000E-06
forstrnps: loop on k-points and spins done in parallel
-P-0000  leave_test : synchronization done...

This job is the second part of "Geometric optimization", the first of which was
completed successfully with keywords "ionmov = 1, optcell = 0". And the
keywords in this job are:
  ntime    500
ionmov    3
optcell     2
ecutsm     0.5
dilatmx     1.1

Hoping your help. Thanks.
