Neal Richardson created ARROW-13507:
---------------------------------------
Summary: [R] LTO job on CRAN fails
Key: ARROW-13507
URL: https://issues.apache.org/jira/browse/ARROW-13507
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Neal Richardson
Fix For: 6.0.0, 5.0.1
ARROW-13199 added -fno-lto flags to the build (see also ARROW-12853). This
likely is the cause of the LTO failure on CRAN:
https://www.stats.ox.ac.uk/pub/bdr/LTO/arrow.out so we probably need to back it
out.
We don't have a CI job that tests with R built with --enable-lto, and AFAICT
there is no docker image out there that has one. I will try to get one added to
wch/r-debug so that we don't have to build R from source to test this.
