Strange behaviour of read and writeBin
To me it seems like writeBin() writes one char/byte more than expected.
> con <- file("testbin", "wb")
> writeBin("ttccggaa", con)
> close(con)
> con <- file("testbin", "rb")
> readBin(con, what="character")
[1] "ttccggaa"
> seek(con, what=NA)
[1] 9
> close(con)

Debugging segfault in foreach
Hi,
I'm using R-2.12 on a linux 64bit machine.
