Hello, I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.
The specification says that: > The test also fails if an exception is raised, assuming the implementation has > a way to catch exceptions. Guile has a way to catch exceptions. However nevertheless the following does not lead to 'fail, but an exception being raised: (use-modules (srfi srfi-64)) (test-begin "x") (test-approximate 1 (throw 'foo) 1) Leading to: Backtrace: In ice-9/boot-9.scm: 1752:10 8 (with-exception-handler _ _ #:unwind? _ #:unwind-for-type _) In unknown file: 7 (apply-smob/0 #<thunk 7fd834112300>) In ice-9/boot-9.scm: 724:2 6 (call-with-prompt _ _ #<procedure default-prompt-handler (k proc)>) In ice-9/eval.scm: 619:8 5 (_ #(#(#<directory (guile-user) 7fd834115c80>))) In ice-9/boot-9.scm: 2836:4 4 (save-module-excursion _) 4388:12 3 (_) In /home/wolf/src/guile-wolfsden/tests/srfi-64/test-approximate-throw.srfi64test: 7:0 2 (_) In srfi/srfi-64/testing.scm: 677:16 1 (_ _ #f) In unknown file: 0 (real-part #f) ERROR: In procedure real-part: In procedure real-part: Wrong type argument in position 1: #f Have a nice day Tomas Volf
