[Pw_forum] How to solve this problem

[Chaohao Hu]

Dear Sir,
During my cacluations about TiH2, the SCF calculations is OK,
But when calculating DOS and PDOS, even I modified my makefile many times after reading manul file, some wrong information about segmentation fault described below still appears in my bash
 terminal. My system is Redhat Linux9.0, the complier is intel-fortran8.1 and numerical
lib is intel-mkl721. In addition, the unit of TiH2 only include three atoms, a primitive cell.
In my previous calculations about other systems, a larger cell is also considered and the program runs very well.
How to solve this problem?
