[Rd] Intermittent crashes with inset `[<-` command

The following code crashes after about 300 iterations on
my?x86_64-w64-mingw32?machine on R 3.5.2 --vanilla.??
Others have duplicated this
(see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I
don't know how machine/OS-dependent it may be.??
If it doesn't crash for you, please try increasing the length of the x
vector.

Substituting the commented-out line for the one below it works correctly (prints
out 1:1000 and ends normally) every time.

x <- 1:200000
y <- rep(letters[1:5], length(x) / 5L)
for (i in 1:1000) {
? # x[y == 'a'] <- x[y == 'b']
? x <- `[<-`(x, y == 'a', x[y == 'b'])
? cat(i, '')
}
cat('\n')

The point of using this syntax is to make it work better with pipes, but the
errors occur without pipes or magrittr.

Thank you for your help!

[Rd] Intermittent crashes with inset `[<-` command

Hi Brian,

I don't have a windows machine, but on a modern macbook pro I'm not able
to
get this to crash in 3.5.1 or a very recent built-from-source R-devel.  I
increased the length of x by 2 orders of magnitude but that just made the
loop take a lot longer to successfully run in both R versions i tested.

So seems like there is some OS/machine dependency at work here (?).

Best,
~G

(see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I
don't know how machine/OS-dependent it may be.It crashes too on my Mageia6 (RPM based Linux distribution):
 ?184 185 186 187
 ?*** caught segfault ***
address 0x700000002, cause 'memory not mapped'

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

The crash can happen at different moments, sometimes after i=187 like in 
the example above, sometimes after i=915. The error is not always 
segfault. It can also be

915 Error in `[<-`(x, y == "a", x[y == "b"]) :
replacement has length zero

or

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Error in 
`[<-`(x, y == "a", x[y == "b"]) :
 ? types (de raw a integer) incompatibles dans l'ajustement 
d'affectation de type

(sorry, this crash was in french locale)

Hoping this helps.
Serguei.

I can reproduce it too. This is the output from valgrind (sessionInfo below):

[Rd] Intermittent crashes with inset `[<-` command

Hello,

I can also reproduce this, R 3.5.2 on Ubuntu 18.04 LTS.


First run gives error after 148.

After 148:

Error in `[<-`(x, y == "a", x[y == "b"]) :
   substituto tem comprimento zero
Execu??o interrompida

Translation:

replacement has length zero
Execution stopped


Second run gives a different error, I changed the script to start with a 
sessionInfo() instruction, everything else is the same as in the OP.

After 180:

  *** caught segfault ***
address 0x700000002, cause 'memory not mapped'
An irrecoverable exception occurred. R is aborting now ...


Several runs with or without the sessionInfo() always give the two 
different errors above.

The sessionInfo() was the following.
