------------------ Additional Follow-up Comments ----------------------------
I've updated our regex code to match Mono's.  However, there is a bug in Mono's 
regex code (which I've fixed in 
our copy).

Line 785 of interpreter.cs does an Debug.Assert on
"cp > mark_start".  This should read "cp >= mark_start".
It works fine in Mono because mcs removes the Assert calls 
from the program due to "Conditional(DEBUG)" attributes.  
Since we are compiling pnetlib in debug mode, the assert 
is compiled into our code and fires.

You may want to report this bug to them so that they
can fix it in future versions of their regex code.

Summary:  program using regex generates run time error - works with m$ and mono

Original Submission:  The attached program generates the following message when 
executed by ilrun:

Assertion failed: Regex

The program compiles with cscc, mono, and m$.  mono and m$ run the compiled 
program, cscc produces the error.

The same error occurs when ilrun is used to execute the code compiled by cscc, 
and when ilrun is used to execute the code (for the same program) compiled 
using mono's compiler.

Create directory, extract files from tar archive, run make.  Run the compiled 
program with the command line:  ilrun ListGenerator String 
TypesafeList.template StringList.cs     To see normal execution change CS in 
the makefile from cscc to mcs
