[Links2004]

• I confirm that this is an issue rather than a question.

Bug report

Steps to reproduce

• build latest master on arch
• start hyperiond
• core dumped

What is expected?

• hyperiond is started and working

What is actually happening?

$ hyperiond

System

[Paulchen-Panther]

Please tell us more about your system. I could only read arch out of it. How did you compile? Which dependencies did you install? Did the config exist from the beginning or did you select the xcb grabber yourself?

Hi,

compiled via https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=hyperion.ng-git
for gdb trace with -DCMAKE_BUILD_TYPE=RelWithDebInfo

config is exsisting and works fine with a older commit (612d1788)

cfg export @ 612d178:
cfg.json

Hi @Links2004
I fixed the issue via PR #1717.
It would be great, if you could apply the patch to your build, retest and provide feedback.

Many thanks in advance!

PS: In case you would like to test the PR without building yourself, you can test the re-build artifacts following the
Testing Pull Requests documentation.

Looks good, no more core dump on startup and the xcb grabber is working.
thanks for the fast fixing.
