Julia aborts from a Scale on mac

[giordano]

I mean, someone needs to follow the code, follow why the assertion is being triggered and understand if this package is doing something wrong (passing garbage to libcairo?) or maybe it's an error inside libcario.

[giordano]

I don't see any segmentation fault, only an abort due to a failed assertion, which is quite a lot different.

[yakir12]

Frustratingly, I have been getting segfaults before, but I can't seem to reproduce one right now. In any case, any ideas why Julia would abort from such MWE?

[giordano]

It isn't julia, it's an internal assertion in Cairo. Quoting from the error you shared:

Assertion failed: (!surface->finished), function _cairo_surface_release_source_image, file cairo-surface.c, line 2092.

Oh... OK. So something closer to this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=114298 and not https://github.com/JuliaGraphics/Cairo.jl?

I tried this on Julia version 1.9.0-alpha1 and got a segmentation fault:

as well as in version 1.10.0-DEV.39:

However, It worked just fine on the current LTS: 1.6.7!

I get segfault as well:

I get segfault as well:

I still don't see any segmentation fault.
