<div dir="ltr"><div>Dirk, Thanks much for taking the time to investigate this issue. I've created a package (sparseList_1.0.tar.gz) with a minimal example of what writing from a list of dgCMatrix matrices at the R layer to a field<sp_mat>. I had intended to install boot2docker and use load your R-devel set-up to a container so that I could replicate the ASAN-generated error. Its taking me longer than I'd hoped, however, so - for now - I include the package tarball with the minimal example and also an R script (sparse_list_to_field.R) so that you may see what the function does. </div>

Terrance,<br>
<br>
So I took a look with one of the prebuilt versions of R using the Docker<br>
container I prepare (see the blog / sanitizers write-up I linked to) as I<br>
realized that we had a Rcpp Gallery post similar to what that as<> conversion<br>
does.<br>
<br>
And no issue with that code.<br>
<br>
>From a brief look at your package it seems like you are pushing the envelope<br>
a lot harder with fields and list of sparse matrices ( in dpmix.cpp, where<br>
another ASAN log pointed to ) so you may have to debug around there.<br>
<br>
A small reproducible example would surely help us. So far I don't have one<br>
for as<sp_mat>.<br>
