Когда я запускаю valgrind в пустом R-файле, у меня появляется полная страница ошибок (см. В конце).
R -d "valgrind --tool=memcheck --leak-check=full" --vanilla -f empty.R
Когда я запускаю valgrind в файле, который вызывает любой C ++Код У меня есть еще одна полная страница ошибок (см. в конце).Например, просто используя такой R-файл:
Rcpp::sourceCpp(code='
#include <Rcpp.h>
// [[Rcpp::export]]
void f() {return; }'
)
Следовательно, когда я тестирую свой пакет с valgrind, я получаю огромный отчет с 8000 ошибками, которые не связаны с моим кодом .Проблема в том, что среди этого огромного отчета могут быть некоторые проблемы, по моей вине.
И действительно, это произошло, и я пропустил свои собственные проблемы, потерянные в беспорядке, и я получил доброе электронное письмо от CRAN, в котором говорилось, что у них есть дела поважнее .
Справедливо, это действительно была моя вина, но вы можете признать, что эти условия трудно было найти.В любом случае мне хотелось бы понять, могу ли я отфильтровать отчет valgrind, чтобы получить что-то читаемое и не пропустить свои собственные ошибки.Почему у меня все это безобразие?Нужно ли переустанавливать R?Я думаю, что это произошло после R 3.5, до этого мои valgrind отчеты были четкими (насколько отчет valgrind может быть чистыми ...)
