I can't find a bug on MOS. They won't open one unless you can reproduce it. If you really want, you have to have multiple sessions doing queries mixed with uncommitted DMLs. _db_block_max_cr_dba's restriction to 6 will be broken if you have multiple users. See
Bug 8802474: RESTRICT NO. OF BLOCK CR IMAGES TO DEFAULT VALUE 6
Still, I don't know how to explain your case, particularly the fact that it only happens to that first level bitmap block.
