Deleting tip in a Body with a Part fusion on the top crashes

Premik · Post by **Premik** » Tue Oct 10, 2017 8:24 pm

Load the attached Crash3.FCStd file.
Navigate to the "Fusion/Body" and delete the last "Pocket1". -> crash.

OS: "Arch Linux"
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.12364 (Git)
Build type: Debug
Branch: master
Hash: 5632f17d813ca74487a045416c7937fcc9103fe3
Python version: 2.7.14
Qt version: 5.9.1
Coin version: 3.1.3
OCC version: 6.9.1.oce-0.18
Locale: English/UnitedStates (en_US)

Note:

Setting Tip manually to a different primitive or removing the topmost Union-Fusion beforehand prevents the crash.
I managed to get to this state by removing multiple primitives before. I can attach the very original file too if it would help.
It appears the Pocket1's base is not the Pad1 but some other primitive I've deleted earlier. But I don't see where I can change a pad's base now. Not sure if this is related to the crash or not.

I've just noticed opening Tools/Dependency graph on the same file crashes instantly too. But with a different trace:

I've just noticed opening Tools/Dependency graph on the same file crashes instantly too. But with a different trace:

Confirmed and fixed with git commit 92ec59d

Navigate to the "Fusion/Body" and delete the last "Pocket1". -> crash.

Confirmed and fixed with git commit 5f86bfc

The crash happened because when deleting the pocket1 the tip of the body becomes a null shape. Now the null shape was passed to the occ algorithms which don't check its validity beforehand and just segfaults later. So, the calling instance (here MultiFuse) must verify the shapes first.

Thanks. I can confirm both issues are fixed.

In the meantime I found another similar one in the Dependency graph. I've attached an earlier version of the file above. Which was before I deleted multiple objects to narrow the original issue down.
Open the Crash.FCStd file, Tools/Dependecy graph => Assertion failed
Is this just because I have a debug build?
