В ответ на этот вопрос я ищу решение для перехвата одной из ошибок, возникающих внутри блока OpenMP, а затем перебросить его с основным потоком после блока OpenMP при вызове кода C++ из R с использованием Rcpp. Другой вопрос, что происходит не так.
Я следил за ответом здесь и пробовал с std::exception_ptr. Кажется, это работает почти на всех платформах и компиляторах, за исключением Fedora с clang-11, использующим libc++. Вот пример:
// 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;
}
Запуск (вам нужно будет изменить путь)

Кажется, он работает на всех других платформах и конфигурациях компиляторов, которые я тестировал. Я попытался сделать пример без Rcpp (пример на чистом C++), но это не приводит к ошибке, показанной выше.
Мотивирующим примером является мой пакет mdgc, который выдает следующую ошибку на CRAN r-devel-linux-x86_64-fedora-clang:
*** caught segfault ***
address 0xffffffff, cause 'memory not mapped'
An irrecoverable exception occurred. R is aborting now ...
Это согласуется с выводом Valgrind.
Обновлять
Вы также получите аналогичные ошибки, если удалите #pragma omp parallel for num_threads(4) reduction(+:out) и #pragma omp critical. т.е. это не связано с OpenMP.
Получение результата
Я выполнил следующее, чтобы получить результаты (например, r-devel-linux-x86_64-fedora-clang от CRAN):

#include <exception>

#include <RcppThread.h>
// [[Rcpp::export()]]
double that_cpp_func(int const n_it){

if(j > -1)
throw std::runtime_error("boh :(");
out += j; // ignore the race condition
}, i);
pool.join();
return out;
}
