[Rd] Antwort: Re: Crash with Unicode and sub (PR#14114)

[g.russell at eos-solutions.com]

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. 

Best wishes,
