(gitlab is uusable; i have to report here.) ecl 21.2.1 gives: > (log 1/6319748715279270675921934218987893281199411530039296) Debugger received error of type: DIVISION-BY-ZERO #<a DIVISION-BY-ZERO 0x7ff5afe6c540> Error flushed. whereas other cl's (i testyed sbcl and ccl) give results like: ? (log 1/6319748715279270675921934218987893281199411530039296) -119.27552 I tested on amd64 (gentoo) and arm64 (debian and netbsd) with identical results. i did not have a musl box or other bsd to test on. run with --no-trap-fpe, the result is #<single-float negative infinity>. another example is: (truncate (log 1/6319748715279270675921934218987893281199418867)) Debugger received error of type: ARITHMETIC-ERROR #<a ARITHMETIC-ERROR 0xffff8f688a40> whereas this works: (truncate (log 1/631974871527927067592193421898789328119941867)) -103 -0.27893066 which of course suggests that the issue is c's long double's precision. it looks like ecl could use an mpq log function; https://github.com/linas/anant might work. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

ASDF 3.3.6 is released
by Robert Goldman 07 Aug '22

07 Aug '22

Dear Lisp Implementation Developers and Maintainers, Today we release ASDF 3.3.6, the sixth bugfix release for the 3.3 release series, and -- it is devoutly to be hoped -- the final one. We urge implementations that are currently bundling previous versions of ASDF -- and especially those bundling 3.3.0 through 3.3.5 -- to upgrade to 3.3.6 at their earliest convenience. As maintainer, my primary role continues to be coordination and some limited quality control. The real work for this release has been done by many contributors and bug-reporters, to whom the Common Lisp community owes a tremendous vote of thanks. Their names are listed on the Changelog, appended below. An extra special thanks is due to my co-maintainer, Eric Timmons, who has provided many fixes and also has overhauled and much improved our regression testing. We *hope* that the next release will be 3.4, introducing new functionality but which, as the numbering suggests, will be backward compatible. Best, Robert * Fix bug loading ASDF system definitions from jar files on ABCL. See !190 * Fix bug with version numbering after reload. See !194 and #94. Thanks to Eric Timmons. * Fix bug in return value of UPGRADE-ASDF. See !195. Again, thanks to Eric Timmons. * Multiple improvements to documentation and tests. Thanks to Nathan Ringo and Phoebe Goldman. * Add clasp support for uiop/launch program. Thanks to Christian Schafmeister. * Miscellaneous minor bug fixes and tweaks. * Don't let *package* binding leak into ASDF compile operations. Thanks to Phoebe Goldman.
