[R-pkg-devel] *** caught segfault *** address (nil), cause 'unknown'

[jérémy Gelb]

Dear R packages developers,

I am the maintainer of the package spNetwork. It has been removed from CRAN
recently because of an issue with the new compiler clang19. The error came
from one of the dependencies: the package BH giving access to the boost c++
library (https://github.com/eddelbuettel/bh/issues/101).

The boost code has been updated since and I had no choice to include it
directly in my own package and remove the dependency to BH because its
maintainer does not plan a new release before december 2024.

However, there is a new error when I submit the package to CRAN (ubuntu
with clang19). The full report is here :
https://win-builder.r-project.org/incoming_pretest/spNetwork_0.4.4.4_20241026_034629/specialChecks/clang19/package/00install.out

The error occurred during the installation of the package, and the message
is not very helpful :

 *** caught segfault ***
address (nil), cause 'unknown'

It seems that the error is happening when loading a c++ module of my
package

Traceback:
 1: Module(module, mustStart = TRUE, where = env)
 2: doTryCatch(return(expr), name, parentenv, handler)
 3: tryCatchOne(expr, names, parentenv, handlers[[1L]])
 4: tryCatchList(expr, classes, parentenv, handlers)
 5: tryCatch(Module(module, mustStart = TRUE, where = env), error =
function(e) e)
 6: loadModule(module = "spatial_index_cpp", what = TRUE, env = ns,
 loadNow = TRUE)


It is rather strange because I have not edited this module since the last
version and the package is installing correctly on other platforms. I also
tried to validate it with rhub and it worked well even with ubuntu and
clang19 :

Does someone have an idea about what could be causing this error during the
installation ? Any help would be highly appreciated.

I have a specific branch in gihtub for this issue :

All the best
