Yambo Community Forum

Dear all,

I am getting segmentation fault for p2y within freshly compiled yambo 3.4.1 r.3187 and QE 5.1.1. The p2y crashes on QE 5.1.1 outputs but works fine on QE 5.0.2. Here is the message as well as I am attaching PP and data-file.xml. Any hints are very welcome.

Best regards.

Segmentation fault

Dear Martin

thank you very much for reporting the problem.
Indeed I tried p2y on a calculation with QE5.1.1. with the same problem.
Using the 5.0.1 with the same input and yambo versions worked fine.
We will look closely at the matter and let you know.

Best

Dear Martin,
the issue should now be fixed both in the svn repository and in the last version you can download.

Best,
Davide

Dear YAMBO developers,

The same segmentation fault occured for p2y in yambo svn rev.70 and QE 5.1.2:

No probems with new yambo 4.0.0 (svn rev. 71).

Dear Vyacheslav Sokolov,
thank you very much for the report.

We'll try to fix the also stable as soon as possible. Meanwhile either use an older version of pwscf or the 4.0.0 yambo version. However be aware that the 4.0.0 is a devel version, thus still unstable. Presently it overcomes all the tests of our test-suite, which however does not mean yet it is a production version.
