Hello, I have updated ABCL from svn and rebuilt it and updated Maxima and rebuilt it with ABCL. It seems to mostly work except that in a new instance of Maxima launched via (require 'asdf) (asdf:operate 'asdf:load-op :maxima) (run) I find that run_testsuite(); pretty soon runs into some errors and grinds to a halt at rtest14 (pretty early in the test suite). However I find that load(orthopoly); before run_testsuite(); seems to avoid the problem. I don't remember that this work-around was necessary in previous versions of ABCL; I probably last updated ABCL a couple of months ago. orthopoly is a Lisp package which is supposed to be loaded automatically when any of the functions in the package are called for the first time, e.g. $hermite has the 'autoload property. Another clue? When I enter quit(); after the unsuccessful run_testsuite(); I get a Java exception as follows. quit(); java.lang.IllegalStateException: Current state = CODING_END, new state = CODING at java.nio.charset.CharsetDecoder.throwIllegalStateException(CharsetDecoder.java:951) at java.nio.charset.CharsetDecoder.decode(CharsetDecoder.java:537) at org.armedbear.lisp.util.DecodingReader.read(DecodingReader.java:261) at org.armedbear.lisp.util.DecodingReader.read(DecodingReader.java:249) at org.armedbear.lisp.util.DecodingReader.read(DecodingReader.java:227) at org.armedbear.lisp.Stream._readChar(Stream.java:1683) at org.armedbear.lisp.Stream.readChar(Stream.java:1513) at org.armedbear.lisp.Stream$16.execute(Stream.java:2393) at org.armedbear.lisp.Symbol.execute(Symbol.java:798) at org.armedbear.lisp.LispThread.execute(LispThread.java:596) at org.armedbear.lisp.mdebug_20.execute(mdebug.lisp:282) (etc ... I've suppressed the rest of the stack trace.) If you can suggest some additional info I could try to gather to aid debugging, I'll be glad to do so. Thanks for your help, and all your terrific work.
