This function returns the native stack trace as a data frame. Each native stack frame corresponds to one row in the returned data frame. Deep function calls come first, the last row corresponds to the running process's entry point.
winch_trace_back()A data frame with the columns:
func: function name
ip: instruction pointer
pathname: path to shared library
is_libr: a logical, TRUE if this entry is from R's shared library,
determined via procmaps::path_is_libr() on the pathname component
On Windows, call winch_init_library() to return function names
for a specific package.
sys.calls() for the R equivalent.
