None of the lines in the function regerr() are executed. See ``lprof Summary Output for a Test Suite''.
To find out why, invoke cscope and request a list of the functions that call regerr(). See ``Browsing through your code with cscope'' for further information on cscope. cscope reports that no function calls regerr(). Because regerr() will never be exercised, it ought to be -- but, for arcane reasons, cannot be -- deleted from the code. You can, though, discount the 19 lines of regerr() in calculating the percentage of code that is covered by the test suite.
