Assert fail const SbVec3f& SoCoordinateElement::get3(int) index == 1 and this->numCoords == 1 #445

Please post your file here, either zip it, or change the extension to zip. BTW, are you compiling libCoin3D yourself? If so, which revision are you using? |
|
File attached. libCoin3D is from Gentoo package media-libs/coin-4.0.0. I did do a custom build of it through Gentoo's build system to remove all optimization so I could see the values related to the assert that were otherwise optimized out. The Gentoo package seems to be getting the source from https://github.com/coin3d/coin/releases/download/coin-4.0.0/coin/Coin/coin.4.0.0-src.tar.gz |
|
Looking at the Gentoo build file for media-libs/coin-4.0.0 I see there are some patches on top of that source file I mentioned. But they are all patches to the CMake build files...no changes to the sources. |
|
I get the same crash with your fix. Also, SoFCRenderCacheManagerP::SoFCRenderCacheManagerP() is not in the stack trace. Here's the whole stack trace: (gdb) bt |

Right. The referenced commit does not really address the same problem as the one you reported here, but it is the same root cause, which is that Arch::BuildingPart set some out of bound index in some libCoin3D node. The debug build of libCoin3D will check for that in the form of an assertion, but the release build works just fine, indicating that there are other safety check in libCoin3D to deal with this situation. So I think it's good enough, although it would be better to make it a soft warning even in debug build rather than a hard assertion failure. But then again, libCoin3D is an external library. With FreeCAD being an open system, any external workbench is free to add its customized libCoin3D nodes, there is no way to prevent this kind of mistake in node setup. On the other hand, the reason I add the sanity check in the referenced commit is because the partial geometry information obtained from this kind of faulty node produces visual defects in my experimental render caching. |

Ok, understood....thanks. I already worked around the problem by recreating without the BIM components Site, Level, etc. Based on your comment, I can also work around this by building libCoin3D with -DNDEBUG. |
I have a simple file with only a slab and a few walls created using BIM Workbench. Will add link to file if that will help.
When I load the file, I see the following output on the terminal:
ArchSite.py(1139)|TopoShape.cpp(1110): failed to get bounding box: Bnd_Box is void
ArchSite.py(1139)|TopoShape.cpp(1110): failed to get bounding box: Bnd_Box is void
Coin warning in [indexedlineset]::GLRender(): Erroneous coordinate index: 1 (Should be within [0, 0]). Aborting rendering. This message will be shown once, but there might be more errors
Then when I set the view to Top and move the cursor to the bottom left corner of one of the walls, FreeCAD asserts as follows:
FreeCAD: /var/tmp/portage/media-libs/coin-4.0.0/work/coin/src/elements/SoCoordinateElement.cpp:179: const SbVec3f& SoCoordinateElement::get3(int) const: Assertion `index >= 0 && index < this->numCoords' failed.
Aborted (core dumped)
