[plt-scheme] ssax-code.ss appears broken under 359.200

I'm using (planet "ssax.ss" ("lizorkin" "ssax.plt" 1 3)) version of 
Lizorkin's ssax package.  I just got around to revisiting a rather 
lengthy  piece  of  regression code that I had built up from his 
xml-tools-tutorial.  All of it had srfi-78 check statements that 
verified its proper functioning.   However, when I ran it again, for the 
first time under 359.200 I get:

Error at position 3044
([GIMatch] broken for  (END . syntax)  while expecting  END source)
uncaught exception: -1

So I did a grep -i --recursive "GIMatch"  and got back the structure for 
this error message in the file lizorkin/ssax.plt/1/3/ssax-code.ss.

This entire regression file ran with no errors prior to installing 
359.200.  I thought maybe you could take a look at the code and see if 
you could surmise what change in mzscheme might have broken ssax.plt.  
It may affect other packages as well.
