When I write a dataset that contains externalptrs as an attribute (default for readr) in a project using renv, I get a segmentation fault.

#> - Project '~/repro' loaded. [renv 1.0.7]

library(qs)
library(readr)

df <- data.frame(x = 1:10)
write_csv(df, "testdata.csv")
qsave(df, "testdata.qs") # save works here

df2 <- read_csv("testdata.csv")
str(df2)
#> spc_tbl_ [10 × 1] (S3: spec_tbl_df/tbl_df/tbl/data.frame)
#> $ x: num [1:10] 1 2 3 4 5 6 7 8 9 10
#> - attr(*, "spec")=
#>  .. cols(
#>  ..   x = col_double()
#>  .. )
#> - attr(*, "problems")=<externalptr> 

qsave(df2, "testdata2.qs") # breaks the code
#>  *** caught segfault ***
#> address 0x19, cause 'memory not mapped'
#> 
#> Traceback:
#>  1: qsave(df2, "testdata2.qs")

The segfault does not show when I use df2 <- as.data.frame(df2), df2 <- tibble::as_tibble(df2), or attr(df2, "problems") <- NULL, or when I run this outside of renv, or when I use df2 <- read.csv("testdata.csv") instead of readr::read_csv().

I am not sure if this belongs here or to renv.

Let me know if you need any further information.
