I'm testing my code on SLC6, and I'm getting a lot of warnings:
/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase/x86_64/root/5.34.14-x86_64-slc6-gcc4.7/include/TArrayF.h: In function 'TBuffer& operator<<(TBuffer&, const TArrayF*)':
/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase/x86_64/root/5.34.14-x86_64-slc6-gcc4.7/include/TArrayF.h:77:27: warning: cast from type 'const TArrayF*' to type 'TArray*' casts away qualifiers [-Wcast-qual]
This is because there's a cast on that line that casts a const TArrayF* to a TArray*, casting away the const-ness. The same happens in TArrayD, TArrayS, TArrayI, TArrayC (and probably some other TArray's that I'm not using). The casted-to type should include the const-ness (or if it's supposed to be non-const, the const-ness in the function definition should be removed).
