Do not revert it now. I think I have a fix which fixes workflow 27. I am testing it locally by building full release.

[davidlange6]

causing memory corruption in the release it seems

[davidlt]

The easiest solution is to remove all the hacks and just do e.g., std::getenv("CMSSW_RELEASE_BASE") + "/external/" + std::getenv("SCRAM_ARCH") + "/data/" + L1Trigger/CSCTrackFinder/data/core_2014_05_15/comp_dphi_8.dat" or similar in the external.

@davidlt , I like the idea

[davidlange6]

ah - sorry - i missed your comments
we can just revert the revert....

[smuzaffar]

no need to re-revert. I just wanted that revert does not go in the history of git.
Anyway, as it is now in so just leave it there for next IB. It will give me more time for tests :-)
