Hi Lili,<div><br></div><div>I had a look at your input files and the issue is likely related to the use of 2 constraints (your unsuccessful job) instead of 1 constraint (your successful job). Optimising multiple constraints is very challenging, and therefore this has not been tested extensively.</div><div><br></div><div>If you provide your structure 'ex1-geo.xyz' then I can check your job and perhaps implement a bug fix if needed.</div><div><br></div><div>Regards,</div><div>Chris <br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, 1 December 2022 at 23:13:27 UTC rassoul...@gmail.com wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Dear all, <br>I am using 2022.1 version of cp2k. But I have the same problem as Chris. I want to optimize the geometry of a periodic system using cDFT. I received Segmentation fault error ("Program received signal SIGSEGV: Segmentation fault - invalid memory reference.") with Hirshfeld constraints. Same as Chris, it is sensitive to the combinations of atoms I use in &ATOM_GROUP. In my case, it only works fine for one combination of atoms and not any other combinations. The input and output files for the successful and unsuccessful jobs are attached. Only the ATOM GROUP in the input files was altered.<br>I Changed the number of nodes, cores, and memory, but it didn't solve the problem. <br>Any advice or tips on how to solve this issue would be greatly valued.<br>Best regards,<br>Lili<br><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Tuesday, March 31, 2020 at 12:21:31 PM UTC-4 <a href data-email-masked rel="nofollow">uca...@ucl.ac.uk</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>This bug has now been fixed in the latest development version of CP2K.
