Segmentation fault (core dumped) with subtractive sphere

Post by HoWil »

Hello,
I do not know if this is already known, thats why I ask here first before entering it into the bug-tracker.

I get a "Segmentation fault (core dumped)" when applying a subtractive-sphere in part-desing onto a specially placed additive-box.

Here the steps to reproduce:
Start FreeCAD-daily
change to Part-Design-wb
Create body
Create additive box
Select XY-Plane and Z-Axis for Attachment (does also work with XZ and Y)
Extra placement: X: -5mm, Y: -5mm, Z: -5mm
Leave dialogue with OK
Select Subractive-Sphere (Subtractive-Box is working)
voilà... it is gone :o

I did test this several times and sometimes I get only
"Segmentation fault (core dumped)"
sometimes I get something like:

Code: Select all

Can somebody using a self-compiled OCCT 7.1.0 check? This would allow us to know if it's a packaging issue or an OCCT 7.1.0 issue.

Out of 8 tries (each time quitting and restarting FreeCAD), FreeCAD hanged only once, the other tries succeeded without trouble (although I find the subtractive sphere parameters rather slow to open, about 3-4 seconds). :?

The issue is with the additive box centred on the BodyOrigin.

:!: you really have to do the step by step procedure which I listed.
Otherwise it is always fine!

@HoWil some questions:
  1. Can you be sure that the version using OCC 7.1 doesn't mix up 7.0 and 7.1 binaries?
  2. Are you sure that the build using OCC 7.1 once worked?
  3. For the build using 7.1 did you have to make any changes in the FreeCAD source code or did it work out of the box? See issue #0001931

HoWil is using the PPA for the 7.1 version. We don't make any changes to FreeCAD. I do get SMESH error on Windows when trying to build FreeCAD with 7.1 on windows https://forum.freecadweb.org/viewtopic. ... 48#p158014 vejmarie said he would take a look. The OSX builds have also been using 7.1 for a while.
