Any click heisenbug segfault

10 posts

When I run todays 81dbddf7c78921893bd3670b5c87771a2f62ec67 and I click on the canvas or anywhere on the tools I get a segfault. Doesn't happen in gdb, so no BT for you. I just thought I tell you before this becomes a week long bisect.

Hello,

the commit 81dbdd is a fix for segfault when clicking without dragging with tool drawLineFree, so it should not segfault when clicking only.

I suspect the heisenburg you are seeing is from debugging build, a problem already fixed by commit,

https://github.com/LibreCAD/LibreCAD/commit/fdf759b452428b91a0664121a2b98603c5553a22

I still need to know how to show the line when dragging.

I bisected to

c9abbfae3efd79be22b359561e1452525f762d9a is the first bad commit

PS: That has nothing to do with dragging. It already segfaults upon mouse-down.

And no, it happens with 23f8811359013e61788d17f4a6fe552c8308d5e0 too. It really is that "next command tip"

Hello,

Please try with the master branch on my repository: https://github.com/dxli/LibreCAD
Or the equivalent patch attached.

If it still segfaults, please tell me in more details on how to reproduce it. Apparently, it doesn't crash here.

Thanks,

Dongxu Li

Something is pretty strange: I'm back on master of the official origin and remade

c8d94e6a5ea044bdb29c2ac0cfa998640b5a6d61

now I don't get the segfault any longer but the cursor is mal-drawn. It is basically without alpha. Any clue?

Hello,

There's a fix for cursor over white background. I am not satisfied with it yet, but at least the cursor is visible over white background.

At least the segfault is fixed, which has a higher priority.

Thanks,
