[3dprinter-general] Bug#1040252: cura-engine FTBFS on some 32bit architectures

[Gregor Riepl]

This is actually a bug in the test and not CuraEngine.

In tests/InfillTest.cpp:104, they format a size_t as %lld instead of 
%zu. %llu works as well, but it's not 100% correct with a 32-bit size_t.

Current upstream HEAD still has the bug, so I'm going to report it there 
as well: 
https://github.com/Ultimaker/CuraEngine/blob/main/tests/InfillTest.cpp#L103
