Return code -6 when running script in Stellarium

[andrey-nakin]

Stellarium fails with error -6 when running my script.
Here are the last lines of Stellarium console log:

...

Hello @andrey-nakin, we need more info and feedback!

The hardware info, steps of reproduction and log file are really important and help us resolve over 90% issues fast. Of course, in some specific cases we need more data, but we ask the required data separately...

I see you are using the deprecated pauseScript() call. After that, at some later point, you exit Stellarium, and during exiting, there is this malloc error.
Does your script initialize the exit from Stellarium?

Do we have to guess all this? https://github.com/Stellarium/stellarium/wiki/FAQ#reporting-a-crash

@andrey-nakin any feedback please

@alex-w sorry for the delay. I'm trying to reproduce the issue and I can't. I can provide a bit more info about the circumstances the error occurred in.

• The app is working in Linux Mint.
• The script a quite big, about 200k.
• The script makes a lot of screeshots and writes them to the disk.
• The script is working for tens of minutes.
• The error occurs in a random manner: the same script may cause it and may finish with zero code.

I'll provide more info when I am able to reproduce the bug.
