As a followup to this question, I am looking for a solution to catch one of the errors thrown inside an OpenMP block and then re-throw it with the main thread after the OpenMP block when calling C++ code from R using Rcpp. The other question is about what is going wrong.
I have followed the answer here and tried with std::exception_ptr. This seems to work on almost all platforms and compilers with the exception of Fedora with clang-11 using libc++. Here is an example:
// openmp-exception-issue.cpp
#include <omp.h>
#include <exception>
#include <stdexcept>
// [[Rcpp::plugins(openmp)]]
#include <Rcpp.h>
// [[Rcpp::export()]]
double that_cpp_func(int const n_it){
std::exception_ptr Ptr = nullptr;
bool is_set = false;
double out(0.);
#pragma omp parallel for num_threads(4) reduction(+:out)
for(int i = 0; i < n_it; ++i)
try
{
if(i > -1)
throw std::runtime_error("boh :(");
out += i;
}
catch (...)
{
#pragma omp critical
if(!is_set){
Ptr = std::current_exception();
is_set = true;
}
}
if(Ptr)
std::rethrow_exception(Ptr);
return out;
}
Running (you will need to change the path)
/root/R-devel/bin/R -d valgrind -e "Rcpp::sourceCpp('/sdir/openmp-exception-issue.cpp'); that_cpp_func(100)"
with the setup below yields the following:

It seems to work on all other platform and compiler configurations I have tested though. I have tried to make an example without Rcpp (a pure C++ example) but this does not produce the error shown above.
The motivating example is my mdgc package which yields the following error on CRAN's r-devel-linux-x86_64-fedora-clang:
*** caught segfault ***
address 0xffffffff, cause 'memory not mapped'
An irrecoverable exception occurred. R is aborting now ...
This is consistent with the Valgrind output.
Update
You also get similar errors if you remove the #pragma omp parallel for num_threads(4) reduction(+:out) and #pragma omp critical. I.e. it is not related to OpenMP.
Producing the Result
I ran the following to produce the results (like CRAN's r-devel-linux-x86_64-fedora-clang):

Using RcppThread
RcppThread equally fails. Consider the following file:
// openmp-exception-issue.cpp
#include <exception>
#include <stdexcept>
// [[Rcpp::depends(RcppThread)]]
#include <RcppThread.h>
// [[Rcpp::export()]]
double that_cpp_func(int const n_it){
std::exception_ptr Ptr = nullptr;
double out(0.);
RcppThread::ThreadPool pool(4);
for(int i = 0; i < n_it; ++i)
pool.push([&](int const j) -> void {
if(j > -1)
throw std::runtime_error("boh :(");
out += j; // ignore the race condition
}, i);
pool.join();
return out;
}
