Description

Firstly, please direct me to a more suitable list if this is not where I should seek help with RcppParallel.

CRAN would like me to fix clang-ASAN and clang-UBSAN issues from RcppParallel when I submit packages 'secr' and 'openCR'. These are completely arcane to me. The problem only seems to arise when running tests. Is there a setting in RcppParallel >=5.1.1 that will get me through?

The test results are at
https://www.stats.ox.ac.uk/pub/bdr/memtests/clang-ASAN/secr/tests/testthat.Rout.fail
and
https://www.stats.ox.ac.uk/pub/bdr/memtests/clang-UBSAN/openCR/tests/testthat.Rout

Here is a typical snippet from the first:

library(testthat)
test_check("secr")
Loading required package: secr
This is secr 4.4.1. For overview type ?secr
../../src/tbb/scheduler.cpp:328:16: runtime error: member call on address 0x7f795c81ff40 which does not point to an object of type 'tbb::task'
0x7f795c81ff40: note: object has invalid vptr

Research direction

Start with src/tbb/scheduler.cpp at line 328 and the linked clang-ASAN and clang-UBSAN test outputs. Reproduce the reports by running testthat::test_check for secr and openCR under the sanitizer configurations. Done means identifying the RcppParallel cause and either eliminating the invalid tbb::task report or documenting the required supported setting.
