The problem existed only in my modified version of R-devel. I had
made a modification so that assignment of an attribute did not copy
the value if NAMED(val) == 0. Up until now we thought that this
modification would be benign and would give a performance boost to
packages that use S4 classes and methods, which means most of
However, it seems this change is not benign. In a sense this is good
news because it will allow us to isolate where the problem lies.
I have not committed this change to r-devel so others need not worry
about the use of a current r-devel breaking Bioconductor.
