+=head2 Eval ... has unknown invoking fid
+
+When using the statement profiler you may see a warning message like this:
+
+ Eval '(eval 2)' (fid 9, flags:viastmt,savesrc) has unknown invoking fid
10
+
+Notice that the eval file id (fid 9 in this case) is lower than the file id
+that invoked the eval (fid 10 in this case). This is a known problem
caused by
+the way perl works and how the profiler assigns and outputs the file ids.
+The invoking fid is known but gets assigned a fid and output after the fid
for
+the eval, and that causes the warning when the file is read.
