[Rd] Crash with Unicode and sub (PR#14114)
Full_Name: George Russell
Version: 2.10.0
OS: Windows XP Version 2002 SP 2
Submission from: (NULL) (217.111.3.131)
The following typed into R --vanilla induces a crash:
-- cut here --
gctorture()
u <- intToUtf8(c(rep(1e3,1e2),32,c(rep(1e3,1e2))))
v <- rep(u,1e2)
v <- sub(" ","",v)
v %in% ""
-- cut here --
sessionInfo() says:
-- cut here --
R version 2.10.0 (2009-10-26)
i386-pc-mingw32
locale:
[1] LC_COLLATE=German_Germany.1252 LC_CTYPE=German_Germany.1252
[3] LC_MONETARY=German_Germany.1252 LC_NUMERIC=C
[5] LC_TIME=German_Germany.1252
attached base packages:
[1] stats graphics grDevices datasets utils methods base
-- cut here --
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.
Best wishes and thanks,
George Russell

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. -- O__ ---- Peter Dalgaard ?ster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.

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.
