Hi Iain,

Yes, gdb is the GNU Debugger.  You can run it on programs that are
compiled with optimization but you won't get as useful information as
all the symbol and line info gets stripped out.  You can run it a
number of ways, but you could try this:

> gdb csound

this will start gdb with csound as the command, once here, type:

> set args test.csd

to set the commandline args (anything after the args will run as if
you typed "csound [args]"), then type:

> r

to run.  It should run until the segfault, then it will come back to
the gdb prompt, where then you type:

> bt

to get a backtrace, which should show you what line the segfault
happened. You could try it before doing the debug build to see what
info you get (probably not much), and then do the debug build and run
again.

You can also set breakpoints, watchpoints, etc. all the things you do
with debuggers within IDE's.  You can type "help" on the gdb prompt to
get more information on what you can do.

Hope that helps!
steven
