Subject: Compiler mis-identifies source location of erroneous parenthesis pairs

In guile 2.0.13, both the compiler and the interpreter
fail to identify the source location of errors of the following
form.  It instead reports the errors as occurring in boot-9.scm.
(unknown-func unknown-symbol () #t)
GUILD COMPILE ERROR
;;; WARNING: compilation of /home/mike/projects/bug1.scm failed:

Yep.  Tough one.  Same behavior in 2.2.
