In my package [1] I open handles to temporary files from c++, pointer to
the objects containing those handles are returned to R as external
pointer objects. The files are deleted when the corresponding R-object
is deleted and the garbage collector runs:
a <- lvec(10, "integer")
rm(a)
Then
pt in memory. But
that is only a partial solution.

The following code crashes R (I know I shouldn't try to estimate such a
model; this was a bug in some code of mine). I also tried with R-devel;
same result.
tab <- structure(list(dob_day = c(FALSE, FALSE, FALSE, FALSE, TRUE,
TRUE, TRUE, TRUE), dob_mon = c(FALSE, FALSE, TRUE, TRUE, FALSE,
FAL
It is actually model.matrix that crashes, not glm. Same crash occurs
with e.g. lm.
model.matrix(dob_mon ~ dob_day*dob_mon, data = tab)
also crashes R.

I suspect that you are looking for something like:
read.csv(textConnection(

As Joris mentioned this question does not belong on R-devel, but on R-help.
When replying to your earlier question I missed that I was replying to

So, please post any follow up questions to R-help.

Apolog
Dirk,
The vagrant setup I use to test my packages with UBSAN also seems to
replicate the error reported by CRAN (together with some other
warnings). I have attached the files (I hope they get through the
filters). I suppose you know what to do with them.

I am trying to use R_RegisterCFinalizerEx to ensure some c++ object is
properly deleted after use. However, I run into some problems when
trying to pass in the third argument which is an Rboolean. The line
'R_RegisterCFinalizerEx(p, finalizer, TRUE);' generates the following
error when t
Rinternals.h. Now that I reread it again, I can see
a slight preference for Rdefines.h, but you really have to read closely.
Thanks again.
