[QE-users] Error in neb.x - double free or corruption

[Suraj P]

Dear QE users,
Im trying to perform the NEB calculation for determining the transition state involved in the Hydrogenation of cresol molecule adsorbed onto a Ni-Cu bimetallic surface. I have relaxed the FIRST IMAGE and LAST IMAGE separately.
While performing neb.x Im getting the following error :
_________________________________________________________
*** Error in `neb.x': double free or corruption (!prev)
_________________________________________________________

I have checked by changing the compiler from openmpi-5.0.3 to intel-mpi-2020-v4. However, the error persists. The version of QE that Im using is quantum_espresso-6.8.
Im have attached the input, the batch script, and the output file.

Kindly help me to troubleshoot the problem.
