Sonar-scanner crashed on a c-file on OSX


Since upgrading to SonarQube 7.5 or 7.6 from 7.4 (developer editions), sonar scanner crashes on analyzing c files on OSX (High Sierra 10.13.6).

My issue is very similar to: Sonar-scanner crashed on a c-file

However, ‘sysctl -w vm.max_map_count=262144’ and ‘sysctl -w fs.file-max=65536’ doesn’t work on OSX (i.e sysctl: unknown oid ‘vm.max_map_count’).

Same setup works fine when using SonarQube 7.4 using sonar scanner (sonar scanner is successful). The problem started in 7.5 and is still present in 7.6.



Hi @dave,

SonarQube 7.5 ships with a new C/C++/Objective-C analyzer, that’s why you are now facing such issue.
In order to help you could you please share a bit more of the log you posted? In particular the full line below.

INFO: [pool-2-thread-1] …file.c

I would then need you to try to create a reproducer for such failure, you would need to run the analysis specifying the following property:


After that you should find a file called sonar-cfamily.reproducer in the project folder and you should share it with me privately if it is not open-source code.

Hi @mpaladin,

I added the sonar.cfamily.reproducer line, after rerunning the job I see in the log:

ERROR: Please contact SonarSource Support and provide file .../sonar-cfamily.reproducer

This appears right before the INFO: [pool-2-thread-1] log line.
However, I don’t see the file where it says it should be. I searched through the entire project folder and its not there?

By the way: I’m running all this on Jenkins.



Hi @dave,

if the reproducer has not been created would you be able to try to create a minimalistic reproducer project to help us with the investigation?

It would also be helpful if you could send me privately the full sonar-scanner log and the build-wrapper-dump.json file.

Hi @mpaladin

What would cause the reproducer file to not be created?

Sure, i’ll try and help. Are you suggesting that I try to create a separate test project to reproduce the error?



the scanner log and build-wrapper-dump.json files might help me to understand.

if you would be able to create a minimal reproducing project that you could archive and share with me that would be great.
