Thanks to Martin, got the B-D installed. With the attached diff, I'm getting: | Running r4rs.test | ERROR: Unbound variable: bar so leaf-eq? seems the buggy one. Still need to go deeper, but I thought I'd let the bug log know. I've also noticed there were other “bar” occurrences in the file, so I've replaced it with “fooish”, but that still breaks in the same way. And if there are other folks who want to play with it, once the build failed, the tests can be run using “make check-TESTS”. Happy everything.

Maybe I'm wrong but that looks like it could be a miscompilation bug. Explanations: since upstream moved from CVS to git, I gave bisecting a try. I used “git merge-base” to find the branchpoint between the 1.6 and 1.8 branches, and try to build there. I had to tweak the environment a bit, but then stumbled upon FTBFS with gcc-4.3. Since I wasn't keen on patching every revision to be tried, I tried with gcc-4.2, and then I couldn't reproduce the test-suite failure anymore. I'm not sure how to debug that any further without having to fix every tried revision, which would mean a dozen or so. I think I'll be lacking either time or skills to fix every build failure, so I'll leave it up to the maintainer to see what to do from now. Mraw, KiBi. signature.asc Description: Digital signature

I just tried to build it with CFLAGS=-g -O0 and the test-suite didn't fail any more. -- Martin Zobel-Helas | Debian System Administrator Debian & GNU/Linux Developer | Debian Listmaster Public key http://zobel.ftbfs.de/5d64f870.asc - KeyID: 5D64 F870 GPG Fingerprint: 5DB3 1301 375A A50F 07E7 302F 493E FB8E 5D64 F870 -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
