everybody,
<br>
<br>
<br>
I have new results considering the lapw0 crash which happens
partially (segmentation fault error - core dump).
<br>
<br>
It seems that the crucial thing is the case.clmsum file. (I am no
expert here) But if this is somehow the key. It can produce the
lapw0 so it might be that it is sometimes triggering the lapw0.
<br>
<br>
I calculated MgF2 and substituted the new generated clmsum by an
older one and then there was no crash. I cannot attach them
because the file size is too large.
<br>
<br>
<br>
I am not so into debugging, to find out why and where it happens.
<br>
<br>
<br>
Best regards,
<br>
<br>
Michael
