segmentation fault as soon as it is run. The solution is to link
against a static version of the library containing the profiling
support code, which for @code{gcc} users can be done via the
-@samp{-static} or @samp{-static-libgcc} command line option. For
+@samp{-static} or @samp{-static-libgcc} command-line option. For
example:
@example
@code{gprof}. @xref{Line-by-line, ,Line-by-line Profiling}.
It also worth noting that @code{gcc} implements a
-@samp{-finstrument-functions} command line option which will insert
+@samp{-finstrument-functions} command-line option which will insert
calls to special user supplied instrumentation routines at the entry
and exit of every function in their program. This can be used to
implement an alternative profiling scheme.
compiled with a @samp{-g} option, in addition to @samp{-pg}, in order
to generate debugging symbols for tracking source code lines.
Note, in much older versions of @code{gcc} the program had to be
-compiled with the @samp{-a} command line option as well.
+compiled with the @samp{-a} command-line option as well.
The flat profile is the most useful output table
in line-by-line mode.
