Not sure about that. I'm doing the bisection now. The bug isn't present in commit 745a16218a43692d2c9ecdad72d1bab73fab0522 from Sept. 7, so it's pretty recent. On Fri, Sep 18, 2009 at 8:35 PM, Joe Marshall wrote: > On Fri, Sep 18, 2009 at 1:57 PM, Chris Hanson wrote: >> FYI, while testing my m

On head, the bug is present; the third compilation fails. So sometime between 3b5c6a1def63320a24c45294afa873fde9194625 (August 24) and now the bug was introduced. I guess it's time to try git bisect. On Fri, Sep 18, 2009 at 4:24 PM, Chris Hanson wrote: > My mistake: I forgot I was testing the s

My mistake: I forgot I was testing the sources from commit 3b5c6a1def63320a24c45294afa873fde9194625. They appear to be fine. I'm now running the same test on HEAD. On Fri, Sep 18, 2009 at 3:24 PM, Chris Hanson wrote: > Yeah, I'm running a test now starting from the 20090107 binary and > compilin

Yeah, I'm running a test now starting from the 20090107 binary and compiling sources from head, and the second compilation is going fine. I'm wondering if there's something wrong with my current binary (and how that could happen). On Fri, Sep 18, 2009 at 3:16 PM, Taylor R Campbell wrote: >   Dat

Of all the recent changes that I'm aware of, I'm thinking that the change I made to expand the CAR/CDR calls in list.scm is the most likely culprit just because it is the file `list.scm'. I can't really imagine what would cause the effect you are seeing, though. I just changed calls to CADR into
