The crash in the issue 2980 was produced by the execution the CbmL1 task with the enabled performance (the third parameter of the CbmL1 constructor). The performance requires MC points and MC-hit matches in the cbmsim. To provide the MC-to-hit match branches, the CbmMatchRecoToMC task should be executed before the CbmL1, which was not done in the version of the run_reco.C, which produced the crash.
This merge request provides a check for the above mentioned branches. The check disables the performance, if at least one of the branches is not provided.
