It seems (from the debugger output) that this is corruption in the R
memory allocation routines. Such things can usually be tracked down
via valgrind and a valgrind-instrumented build of R, but I cannot
trigger this on any system with valgrind. I've tried 64- and 32-bit
versions, and Latin-1 locales as well as UTF-8.
So I am inclining to think this is Windows-specific. One thing that
is specific to Windows is UCS-2 (16-bit) wide characters, which might
be the issue. But we simply don't have the tools on Windows that we
do on other platforms.

Hello Peter,
I have now installed R-2.10.1 RC (sessionInfo() says "R version 2.10.1 RC
(2009-12-06 r50684)", the rest I believe is as before). The following code
always brings R --vanilla down (with a crash, not a normal exit):
-- cut here --
gctorture()
u <- intToUtf8(c(rep(1e3,1e2),32,c(rep(1e3,1e2))))
v <- rep(u,1e2)
v <- sub(" ","",v)
v %in% ""
q()
-- cut here --
I've tried this several times now, with different effects. Sometimes R
crashes after 'v %in% ""'. Sometimes it survives that command, but crashes
during the q(). I have also had the error message "Fehler in match(x,
table, nomatch = 0L) > 0L : Vergleich (6) ist nur für atomare und
Listentypen möglich" from that command (the match seems to be the
problem), when I type q() R still crashes.

I apologise for not testing this with R-2.10.1 but as far as I can
see there are
only source releases available so far, which I am not able to compile.
2.10.1 RC is available now. Please check. It does seem to be
reproducible in the Windows version, or at least it takes a very long
time, but that means running under Wine on SUSE for me. I don't see the
effect with the Linux build.
