Hi. Your file crashes too. Must be my install. Anything I could try?
TIA

Not really
(and I have to leave now for some ~2h - maybe someone else has suggestions)

Ok. One observation: the icon at the lower right of the fitsviewer window which restores default slider positions is missing in the git version but present in the stable PPA version.
Ubuntu 18.04

Steve, I'll also take a look. You say it crashes from the most recent git with that file. What computer, OS, other details are you using?

Also, that magic wand icon in the lower right is disabled when the image is already using the automatically computed stretch parameters. It only appears after the stretch has been modified. Perhaps that's what you're seeing?

Hi. Yes, I only see the icon after I move the sliders in the stable version of kstars but in the latest git I never get to see it because moving any of the sliders causes the crash: bt above. It crashes with ANY .fits file whether I created it with a dslr in kstars or not.
Thanks for taking a look.

Ubuntu 18.04 updated
Tried on an intel i3 with 16Gb, an intel i5 with 8Gb both using ssd drives and an AMD E2 with 4Gb and a mechanical hard drive, all using either yesterday's or today's git. The fitsviewer of stable version 3.3.9 works on all three.
TIA

So if I interpret the crash happens during the display of the scaled-down preview in the upper left (cute feature BTW!), and within some QT GL-routine(?)...
Just to be sure - did you do a full clean build from scratch, or use some old(er) CMake cache?

FYI, I am also looking at it, and that "cute feature--upper left preview" is actually some kind of bug I'm chasing down, perhaps a clue to the crashes.
I never programmed that, and it didn't happen previously :/

Unfortunately, I'm having issues with my build environment on my mac, so it may be a bit until I can fix that and then start debugging.

Full clean build from nothing. I deleted ~/Projects and started over: same crash with any .fits file. The bt suggests:
home/steve/Projects/kstars/kstars/fitsviewer/stretch.cpp:321
Had something to do with it,but I'm not a coder...
Thanks for your time everyone.

To reproduce the crash:
1. Open a . fits file in fitsviewer
2. Move one of the three sliders at the bottom of the fitsviewer window.
result: kstars crashes

Thanks again,
Steve

Oops
So maybe some change in the QT libraries? What are you using? I had just updated to 5.14

I found a (my) bug the fitsview code, and submitted a change for Jasem's review. phabricator.kde.org/D26910
I'm not sure that this is causing the crashes, I wasn't able to reproduce them,
but I suppose it's possible. It does, however, clear up the "cute feature--upper left preview"
Steve: once this is submitted (after Jasem's review), please retest. I'll post here when I see that it's in the latest kstars code.
Sorry about that,
Hy

It is now submitted, so if you git pull and compile, you'll have the fix.
Not sure when it gets to the nightly release? A day or so?
Please test and let me know.
Hy
