 Priority:  minor        |             Milestone:  someday

-------------------------+--------------------------------
 Compiling this kills the compiler (note the spurious dot):
 `(: foo (pair * . *))`

 {{{
 Error: during expansion of (: ...) - segmentation violation

         Call history:

         <syntax>          (##core#begin (: foo (pair * . *)))
         <syntax>          (: foo (pair * . *))  <--
 }}}
