I can't reproduce the bug on linux.

- What is the exact procedure to make QLC+ crash ? (which options do you pass to QLC+, what buttons do you click on once QLC+ is started...)

- Does OSX give you informations other than "Segmentation fault" ? Like a backtrace or something ?

I'm sorry but this is not sufficient. We need a lot more details.

As an example, that's what I did to test this bug:
- I start QLC+ with the -w option
- I load the workspace you uploaded here workspace
- I type localhost:9999 in the address bar of my browser to get to the web access page of QLC+
- I click on the Red Scene button on the web access page
- It works (the scene is started, there is no crash)
The order in which you did things may also be important.
Thank you.

Hi here are the steps.

1. load Qlc+ from terminal with the -w web protocol. This opens up QlC in a New Workspace
2. Open chrome on iPhone and go to the Qlc Web Api page
3. Add the host with :9999
4. Load my IanTestWeb.qxw file from google drive
5. Back in the Mac computer the file opens but says New Workspace as the name in top bar. (This may be problem?)
6. Click on button on iPhone "Red Scene" (should I see anything in program on Mac change accordingly? I don't see anything triggering.
7. I then click on green arrow to try in Operate Mode
8. Then click Button on iPhone and now crashes after putting QlC into Operate mode.

Hope that helps?
Again, all the same steps using Chrome on MacBook work as expected and trigger the scene

Thanks a ton!

Hello!
Using Android device with same steps things seem to work as expected. Maybe there is a bug with iOS?
Cheers!

Hi,

I tried with an android device too, and another computer, and I can't reproduce the crash.

Maybe an issue with iOS chrome. I won't be able to work on this issue, sorry.
