A different assertion in allegro

[Leland (AudacityTeam)]

Hi Roger,

Got this one too on Windows and OSX.  Same steps to reproduce, but with
the following midi file:

http://www.homerow.net/audacity/test.mid

---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Assertion failed!

Program: ...
File: c:\documents and settings\administrator...\allegro.h
Line: 619

Expression: i >= 0 && i < len

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts

(Press Retry to debug the application - JIT must be enabled)

Abort   Retry   Ignore
