#484: -scrutinize not properly expanding match macro.
 Reporter:  alanpost  |       Owner:       
     Type:  defect    |      Status:  new  
 Priority:  major     |   Milestone:  4.7.0
Component:  compiler  |     Version:  4.6.x
 Keywords:            |  
 I've encountered a problem using the match macro while having
 '-scrutinize' enabled.

 I've attached a .scm file that uses the match egg testing four cases.
 Compiling this file with the following command:

 csc -feature compiling-extension -setup-mode -s -scrutinize -j testegg -o testegg.scm

 Gives me the following error:

 Error: (caddr) bad argument type: *

         Call history:

         <syntax>          (##core#let ((g670 ((make-bar "aisa" #f #t)
 "baz"))) (g670))
         <syntax>          ((make-bar "aisa" #f #t) "baz")
         <syntax>          (##core#let ((g672 (make-bar "aisa" #f #t)))
 (g672 "baz"))
         <syntax>          (make-bar "aisa" #f #t)
         <syntax>          (##core#begin (g672 "baz"))
         <syntax>          (g672 "baz")
         <syntax>          (##core#begin (g670))
         <syntax>          (g670)
         <syntax>          (newline)
         <syntax>          (##core#undefined)    <--

 Error: shell command terminated with non-zero exit status 17920: /opt
 /chicken-master/bin/chicken testegg.scm -output-file testegg.c -dynamic
 -feature chicken-compile-shared -feature compiling-extension -setup-mode
 -scrutinize -emit-import-library testegg

 This code compiles fine in the following conditions:

 * it runs fine in csi, this problem relates to the compiler.
 * it runs fine if you comment-out all but one case in match.  The
 particular case doesn't matter, so long as there is only one of them.
 * it runs fine without the -scrutinizer command-line option.

 I've confirmed this problem on experimental
 (df0bb192a6ac069e9d845d8445d96bf173e117fa: updated manifest) and 4.6.0.
 I'm running OpenBSD 4.8.  C-Keen has confirmed this problem with Chicken
