FreeCAD crashes - Bug?

[schloeri]

Hello everybody,

Since version 0.17 I cannot use FreeCAD any longer. When I start FreeCAD I can open an existing file. With one file I cannot even click on the part in the 3D, with another file I can click on the parts in the 3D but when clicking on the part in the tree view FreeCAD crashes.
Running from the console I get "Speicherzugriffsfehler" ... "Memory access error".
Versions:
FreeCAD OS: "openSUSE 13.2 (Harlequin) (x86_64)"
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.7402 (Git) (Packman)
Build type: Release
Branch: master
Hash: 3e941f2b8742c895e7ad3ef1b30d7eae73ae4eca
Python version: 2.7.8
Qt version: 4.8.6
Coin version: 4.0.0a
OCC version: 6.8.0.oce-0.18-dev

Linux kernel 3.16.7

Am I correct here or do I need to post that problem anywhere else?

Cheers, Stefan

Please do

Code: Select all

$ sudo zypper in FreeCAD-debuginfo glibc-debuginfo
$ gdb /usr/bin/FreeCAD -batch -ex "run"
-ex "bt full" -ex "q"

let FreeCAD crash and
provide output then.

It seems it is openSUSE 13.2 only. On 13.1 and Tumbleweed it seems to work properly.

thanks for the reply.

FreeCAD 0.16 worked well on my openSuSE 13.2 system.

I installed the packages and ran the command. I did the same where FreeCAD 0.17 crashes. It did not terminate as without running under the gdb command but it stalled. The output of gdb is massive and it does not stop so I can only post the lines of just before I <Ctrl><C> the gdb command. The output gdb started with

I hope this helps as I am not into debugging.

Hello schloeri! Welcome to FreeCAD and the forum
First, thanks for the quality of your 2 first posts. You provided the necessary information in a clear and concise manner. And the help forum is the perfect place to triage potential bugs.

I'm not on openSuSE, so this might be a wild goose chase. But what version of libboost are you using?

[schloeri]

thanks, I do what I can

The libboost libraries (date_time, filesystem, iostreams, program_options, python, regex, signals, system, thread) are version 1.54.0

[sgrogan]

thanks, I do what I can

Thanks again, shot in the dark worked. Nasty bug in libboost 1.54. Older and newer versions work. Not sure how to fix but this is definitely the problem.

[schloeri]

ok, thanks for the hint.

Interestingly that library version runs on my computer since February 2015. I have been using FreeCAD since then so something must have changed within FreeCAD

Hello Stefan,

FreeCAD OS: "openSUSE 13.2 (Harlequin) (x86_64)"
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.7402 (Git) (Packman)

This version brings many disruptive changes to the Part Design workbench (it includes what devs and regular users call "PartDesignNext", since it's the next generation for this workbench), and there are many bugs to fix, as it is the early start of the 0.17 development cycle, and many things don't work like they used to. Theses changes are the reason why Boost 1.55+ is required.

Unless you want to experiment the new features and participate in bug hunting, it is best to stay with 0.16.6700, which was released just last week. Even better would be to have both installed on your system, 0.16 for regular work and 0.17 for testing.

[schloeri]

ok, let me try to downgrade to FreeCAD 0.16

In the meantime I did install libboost 1.56 and 1.58 (not beside each other).
FreeCAD would not start at all. I then did symbolic linking from all libboost-*.1.54.0 to libboost-*.1.5(6 or 8).0. At least FreeCAD did start but no luck with opening a file -> crash. I went back to libboost 1.54

I just saw when starting FreeCAD that the internal console prints

Code: Select all

Unhandled std::exception caught in GUIApplication::notify.
The error message is: Keine Berechtigung

You cannot simply change the Boost version, you need to recompile FreeCAD with a specific Boost version.
