I'm seeing the same issue. Installing the latest R-Forge .zip of data.table built using 2.15.0 patched, on R 2.15.0 (or 2.14.1 same issue), then running data.table(a=1:3) produces the "7 arguments passed to .Internal(identical) which requires 6" error. traceback() and debugger() just display the top level call. debug(data.table) and stepping through reveals it is a call to identical () but just a regular one. No .Internal() call in the package, let alone passing 6 or 7 arguments to .Internal. Not sure how else to debug or trace it. R-Forge is byte compiling data.table using R 2.15.0 patched (iiuc), would that make a difference when the byte code is loaded into 2.15.0 which doesn't have the new argument in identical()?
