[manifold] Minkowski failed with error, falling back to Nef operation: CGAL ERROR: assertion violation!

[Loki44]

Describe the bug
Rendering the code below produces the following error when the "manifold" option is turned on, it renders fine when it's off:

File: /mxe/usr/x86_64-w64-mingw32.static.posix/include/CGAL/Convex_decomposition_3/SM_walls.h
Line: 438
Explanation: wrong handle

ERROR: Rendering cancelled by exception CGAL ERROR: assertion violation!

To Reproduce
Steps to reproduce the behavior:

1. enable manifold option
2. open code
3. click render
4. wait
5. See error

Expected behavior
it renders without error

Code reproducing the issue
It's also in the attached .txt file, apologies if it's not the best, I'm still pretty new with this.

tiny = 0.001;

$fa = $preview ? 12 : 1;
$fs = $preview ? 2 : 0.5;

module chamfer_text(words,text_width,text_height,font){
    difference() {
        linear_extrude(height = text_height) {
            resize([text_width,0,0], auto=true) {
                mirror([1,0,0]){
                    text(text = words, valign = "center", halign="center",font = font);
                }
            }
        }

        minkowski() {
            difference() {
                translate([0,0,text_width+tiny]) {
                    cube(text_width*2,center=true);
                }

                linear_extrude(height = text_height) {
                    resize([text_width,0,0], auto=true) {
                        mirror([1,0,0]){
                            text(text = words, valign = "center", halign="center",font = font);
                        }
                    }
                }
            }

            cylinder(h = text_height , r1 = tiny, r2 = 1);
        }
    }
}

chamfer_text(words = "test", text_width = 50, text_height = 1.5, font = "Liberation Sans");

[pca006132]

works now in latest master

[nophead]

I get this warning with the latest snapshot 2024.01.26 (git 358af34)

WARNING: [manifold] Minkowski failed with error, falling back to Nef operation: CGAL ERROR: precondition violation!

Older versions with manifold work. E.g. 2023.12.02 (git dbc52d7)

The rendered result looks OK though. I can't see anything wrong with it but I have stop on first warning set so my test fails.

[pca006132]

@nophead can you try e7cf02b and the commit after it, i.e. test if this is due to manifold update.

[nophead]

They are more than 30 days old so the artifacts have been deleted.

[t-paul]

I have triggered a rebuild of the 2 commits:
Before: e7cf02b - https://github.com/openscad/openscad/runs/21200701406
After: d212319 - https://github.com/openscad/openscad/runs/21200704501

[nophead]

Thanks, they both give the same error message.

[nophead]

It is a shame because the older versions that don't give this error on Minkowski have the convexity bug.
