but I have a concise reproducible case that I wanted to share.
Also, please note the Bioconductor scenario which is potentially
seriously impacted by this.
The issue arises when a binary version of a package (like my example
package below) is built under R 2.15.0 Patched but then installed
under R 2.15.0. Our package AnnotationDbi (which hundreds of other
packages depend on) is impacted by this issue to the extent that
calling virtually any function in it will return something like this:
Error in ls(2) :
7 arguments passed to .Internal(identical) which requires 6
My concern is that when R 2.15.1 is released and Bioconductor starts
building all its packages under it, that R 2.15.0 users will start to
experience this problem. We can ask all users to upgrade to R 2.15.1
if we have to, but it's not usually the case that a minor point
release MUST be installed in order to run packages built under it
(please correct me if I'm wrong). We would much prefer a workaround or
fix to make an upgrade unnecessary.
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()?
Yes it would.
