I'm trying to troubleshoot a case where R crashes on Windows. It does
not occur at all with my R v2.1.0 patched (2005-05-09), but happens on R
v2.1.1 (patched or non-patched) in many different cases. The R
v2.2.0dev (2005-07-15) also got this problem (although it won't crash on
the below example). I previously reported this
(https://stat.ethz.ch/pipermail/r-devel/2005-June/033772.html) and
Duncan Murdoch kindly offered to look into the problem, but it is
tricky. Now I would like to track down in what patched R v2.1.0 the
problem first occurs and are now looking for reports from newer version,
but pre-Rv2.1.1.
If you've got R v2.1.0 patched for Windows *after 2005-05-09*, could you
please try the following in that version of R?
install.packages("R.oo")
library(R.oo)
author <- "dummy"
rdocFile <- system.file("misc", "Exception.R",
package="R.oo")
cat("# Empty example code\n", file="Exception.Rex")
Rdoc$compile(rdocFile, destPath=tempdir())
print("successful!")
If you see "successful!", that version is "ok", otherwise R
will crash
(or alternatively incorrectly complain about an invalid regular
expression; rerun and it will crash the 2nd time). I would appreciate a
lot if you report to me what you get and what is your version of R?
Thanks a lot!
Note that this is most likely *not* due to R.oo (no native code) - my
wild guess is that it has to do with a memory leak in the code for
environments or regular expressions.
Thanks

I've tried your example code also in Linux, and indeed I do see quite some memory growth of the R process, particularly if I run for(i in 1:40) Rdoc$compile(rdocFile, destPath=tempdir()) ## which takes a few minutes my R process size grows considerably (50% - 100% depending on the measure I use in 'ps'). So I can confirm that your guess about memory leakage {or something close} seems quite on target. But please don't ask me to dig further here - not for the time being, at least. BTW, I get 10 warnings, both in R 2.1.0 and in 2.1.1 patched (see below) --- but that's probably something not really relevant here. Martin
