Slic3r doesn't slice much models, and it crashes if I try to cancel the slicing (avoid crossing perimeters)

[Liger0]

Version

1.42.0 alpha 4

Operating system type + version

Win10 x64

3D printer brand / version + firmware version (if known)

All printers (also custom)

Behavior

If I load a model and I try to slice it, slic3r will never end the process.
If I try then to cancel it, slic3r just hangs and crashes.

Project File (.3MF) where problem occurs

stuck at slicing.zip

disable "avoid crossing perimeters"

Thanks, it worked.
Since most of the models just make slic3r crash and the option makes it unstable, why not deleting that option at all? If it needed some minutes I'd understand it since there is a warning in the options, but not even hours are enough.

I did not know it is unstable, I just thought it is slow and it generates questionable paths.

The speed of the "avoid crossing perimeters" feature has been improved with 3addae3. This issue is similar to #1756 #2040 #2458 #2546 #2631 #2783.

G-code export of your model takes 5m 40s with the "avoid crossing perimeters" enabled, while it takes 23s to export the G-code with "avoid crossing perimeters" disabled.

I am closing this issue. The "avoid crossing perimeters" is working, it could be canceled reliably. It could be faster, but it finishes in reasonable time.

I am leaving #2213 open for reference of a model, which takes really long to export G-code.
