Bug ID: 381276
Summary: okteta fails to link liboktetacore because of memset
call in bytearraymodel_p.cpp (?)
Product: okteta
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: grave
Priority: NOR
Component: general
Assignee: kosse...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
Created attachment 106124
--> https://bugs.kde.org/attachment.cgi?id=106124&action=edit
workaround: convince the compiler that fillLength can never be 0 (and if it is,
don't register a modification)
I'm seeing an error when building okteta 17.04.2 with GCC 7.1 that was reported
5y ago already (311098). Not sure what to make of it, but it blocks my build:

Whatever the error, the same workaround "fixes" it.
