It did not. It failed when compiling sc/qa/unit/ucalc_formula.o, because
of

/home/tdf/lode/jenkins/workspace/lo_gerrit_master/Gerrit/Gerrit/Platform/Linux/sc/inc/address.hxx:340:5:
error: assuming signed overflow does not occur when assuming that (X + c) < X is always false [-Werror=strict-overflow]
    if ( rAddress.Row() < Row() )
    ^

Which is not caused by your patch. Someone has likely already fixed
this, so you can rebase the change to current master and push to gerrit
again.
