[Rd] error in memCompress() in make check

[Petr Savicky]

Dear R developers:

When i run "make check" in R-patched_2011-02-12 and R-devel_2011-02-22
on a specific machine, the test fails and the file

  tests/Examples/base-Ex.Rout.fail

ends with

  > txt.xz <- memCompress(txt, "x")
  Error in memCompress(txt, "x") : internal error 5 in memCompress
  Execution halted

The error may be reproduced using commands

  txt <- readLines(file.path(R.home("doc"), "COPYING"))
  txt.xz <- memCompress(txt, "x")

in both the above installed versions. The machine is CentOS
release 5.4 (Final) under VMware.

I did not observe this error on other machines, some of which are
also CentOS.

For the development version, sessionInfo() is
