bug#24647: SRFI 64 − Test marked as passed when it should have been marked as fail

[Amirouche Boubekki]

The code for SRFI-64 does implement error catching, but that it might 
return #f if an error happens causing a passed test when it should have 
been marked as FAIL

(use-modules (srfi srfi-64))
(test-begin "repository")

(test-equal
    #f
  (throw 'key))

(test-end)
