+# Running R code with the C++ debugger
+
+As Arrow has C++ code at its core, debugging code can sometimes be tricky when
+errors originate in the C++ rather than the R layer. If you are adding new
code
+which triggers a C++ bug (or find one in existing code), this can result in a
+segfault. If you are working in RStudio, the session is aborted, and you may
+not be able to retrieve the error messaging needed to diagnose and/or report
+the bug. One way around this is to find the code that causes the error, and
+run R with a C++ debugger.
+
+Firstly, load R with your debugger. The most common debuggers are `gdb` and
`lldb`
