Hi, gentlemen,

I’m on a RedHat 7 linux-x86_64 architecture.  I don’t have the ability to
upgrade the sequencer stuff easily because I’m not root on this machine.
However, I will put in the request to upgrade to 2.1 (I’m assuming that
this is the right version).

Kay gave me a few pointers on debugging the file, and he stated that it
might be a memory allocation problem in C which I assumed was the case.
I’m attempting to learn and utilize gdb and valgrind to find out what I’m
doing wrong.  He also gave me a few pointers on how to do things a little
more cleanly in my code.  We’ll see.  I’ll let you know how it goes.

Dave
