The following stratego code works fine when compiled with either strc or strj. When used in the interpreter, both matches fail.

  !"aaa"{"bbb"}
; where(try(?"aaa"; debug(!"Match aaa: ")))
; where(try(?"aaa"{"bbb"}; debug(!"Match aaa{bbb}: ")))

Output of compiled version:

Match aaa: aaa
Match aaa{bbb}: aaa

This is a Stratego issue: I moved it to StrategoXT/806.
