On line 4618 of src/misc.cpp of the lrstat package, you have a
suspicious default parameter value:
>> const int n = NA_REAL
NA_REAL is a special kind of NaN, and C++ signed integers cannot
represent NaNs. You probably meant NA_INTEGER.
I think that Rcpp::traits::input_parameter takes care of
asking R to cast NA_REAL to NA_INTEGER, so this shouldn't directly
cause problems, but without a link to the code and the full error
report we have to resort to forbidden OSINT techniques [1], which don't
always work reliably and may attract the wrong kind of attention on the
darknet [2].

Yes.
If you use containers, try the rocker/r-devel-ubsan-clang [3] image
that should already contain a "sanitized" build of R produced with the
clang compiler.
If that doesn't help, start with a Fedoda 36 installation and follow
the description [4] to install clang and compile R from source with
sanitizers enabled. This procedure is described in more detail in WRE
4.3.4 [5].
If you start having problems using the Docker/podman image or compiling
R from source, don't hesitate to ask further questions.
