Strange Segment Fault

[newdep]

Hi Lutz,



Linux 8.5.10



This file generates very very randomly a Segmentation Fault!

Although the application works fine on my Linux machine somehow

it does crash. Its odd and im unable to detect where its

located. Though I think it has to do with 'write-file !
