Error when initialize a branch of type vector<bitset<256> >


I met a problem when try to initialize a branch of type vector<bitset<256> >. I got this error in run-time:

The class requested (vector<bitset<256> >) for the branch “MuonHltMatchBits” is an instance of an stl collection anvoid to write corrupted data.

Anyone know how to solve this?

Thanks in advance.


Please provide the following information:

ROOT Version (e.g. 6.06):
Platform, compiler (lxplus6, CMSSW_8_0_27):


do you have a dictionary for that class, e.g. did you specify that in the classes.xml within the cmssw package you are developing?


it seems that there is an error in the way the message is being pasted.
