Dear Professor Ripley,
a. I apologise for not including the file. I sent the E-Mail to=20
R-bugs at r-project.org with an attachment, but the attachment evidently got=20
lost. However the text of the file is as follows:
--- CUT HERE ----
gctorture()
characters <- intToUtf8(200:300)
indices <- rep(sequence(5),10)
substrings <- substring(characters,indices,indices + 5)
factor(substrings)
--- CUT HERE ---
b. There is no Unicode file involved, the Unicode comes from the=20
"intToUtf8" function.
c. The operating system is Windows XP Professional (2002), Service Pack 2.
d. I have just tried installing R 2.9.2. This also crashes.
Best wishes,
George Russell

Re: [Rd] Memory-management crash with UTF-8 on Windows (PR#13955)
Without the file, we can do nothing with this, so please put it=20
somewhere accessible. Also, we need exact reproduction instructions:=20
how did you tell R this was a UTF-8 file? If you copy-pasted it, what=20
did you copy it from?
The posting guide and FAQ did ask you not to report on obsolete=20
versions of R, so please do test a current version before replying=20
with details of where the file is.
It would also be helpful to have your exact OS, as the error appears=20
to be in MSVCRT.dll, an operating system component.
