@Riddell: KDevelop on Neon is still using LLVM 5.0?

Could you try to upgrade this to the latest available LLVM version?

Comment 2 Kevin Funk 2018-11-20 15:51:54 UTC

@Reporter: Which project was loaded? Can you disclose the source code? 

Can you nail down which file KDevelop was parsing last (please check the debug output on the terminal for this)?

I have both LLVM 5.0 and 6.0 versions installed and the default is the LLVM 6.0. I need LLVM 5.0 because some package depends on it and so I can't uninstall it. I think it should be up to KDevelop to choose the newest LLVM

Comment 4 Jonathan Riddell 2018-11-21 10:31:05 UTC

Our KDevelop builds against llvm-5.0-dev.  I can switch that to llvm 6 if that helps which is the default in Ubuntu 18.04

Comment 5 Kevin Funk 2018-11-21 10:42:52 UTC

The later the better usually. Thanks for taking care of it!

Unfortunately, this is a closed source project. I can't provide this info.

Comment 7 Jonathan Riddell 2018-11-21 13:43:29 UTC

New build of kdevelop 4:5.3.0-0xneon+18.04+bionic+build7 uses llvm and clang 6 in line with mesa and other parts of Ubuntu 18.04.  This may stop symbols clashes.

Thanks, testing right know the new build.

Should not have been a problem in this case. This rather seems like a crash in libclang while parsing code.

I'm not able to reproduce the crash anymore. I think you can mark this as RESOLVED / FIXED.

Comment 11 Kevin Funk 2018-11-22 10:33:07 UTC

Thanks for feedback. I presume the LLVM/Clang upgrade did the trick.
