Hug v25 Bug [SOLVED]

I noticed yesterday that there is a version 25 of Hug (I have been using v24). So I replaced my old version and tried to compile the project I was working on. However immediately after starting the conversion, bacon threw an error:


Starting conversion... 33
ERROR: could not parse line 33 in file 'hug.bac'!


Thinking there was an error in my project, I tried compiling something simple like this example:
SETENVIRON "LANG", "C"

INCLUDE "hug.bac"

SUB populate_list(NUMBER widget, long* data)

   variable$ = (STRING)*data

   PRINT variable$

END SUB

CONST wintitle$ = "test"
mainwin = WINDOW(wintitle$, 800, 390)

frame1 = FRAME(780, 70)
ATTACH(mainwin, frame1, 10, 10)

button = BUTTON("test button", 110, 50)
ATTACH(mainwin, button, 20, 20)

data$ = "TEST WORKS"
CALLBACKX(button, populate_list, ADDRESS(data$))

SYNC

DISPLAY

But I still got the same error. I then tried rolling back to bacon version 18 but still had the same results. Here is a list of what I tried:
bacon (bacon version) v19
bacon (bash version) v19
bacon (bacon version) v18

All had the same result with Hug v25. If I use version 24, there are no problems. Also tried multiple versions of Hug v25 to rule out a copy/paste issue.

I compared the two hug files, but don't see anything that would cause a problem. Any ideas?
