To debug this try debugmode(true); (%i14) orbits(x+y^2, 0, 100, 400, [x,1,1.53,0.001], [pointsize,0.9],[ycenter,1.2], [yradius,0.4]); Graph passed to plot2d...

Comment By: Raymond Toy (rtoy) Date: 20090504 14:45 Message: Ok. Since this appears not to be repeatable, I'm marking this as Pending/Works For Me. If there's any additional information, please update this bug report.  Comment By: Nobody/Anonymous (nobody) Date: 20090501 17:48 Message: ($i1) run_testsuite(); ... No unexpected errors found. ; Evaluation took: ; 162.15f0 seconds of real time ; 133.21613f0 seconds of user run time ; 20.53623f0 seconds of system run time ; 350,844,228,618 CPU cycles ; [Run times include 9.95f0 seconds GC run time] ; 0 page faults and ; 9,363,027,080 bytes consed. ; (%o0) done Now *that* is interesting... I'd like to say "nevermind"  but now I'm very puzzled. Just for completeness: (%i1) z:0.5+%i; (%o1) %i + 0.5 (%i2) expintegral_chi(z); (%o2) 1.341686846905066 %i + .4971469507996198 (%i3) conjugate(expintegral_chi(conjugate(z))); (%o3) 1.341686846905066 %i + .4971469507996198 and (%i7) 0.5*(expintegral_e(1,z)+expintegral_e(1,z)+log(z)log(z)); (%o7)  0.5 ( 2.683373693810132 %i  .9942939015992396) (%i8) expand(%); (%o8) 1.341686846905066 %i + .4971469507996198 This seems to match your results (except for a bit more precision). At this point, I have no idea how the first test_suite() went wrong, and can't replicate it. Chalk it up to a gravity wave.  Comment By: Nobody/Anonymous (nobody) Date: 20090501 17:28 Message: I'm using the MacOSX build  not building from source. I ran the entire test suite  these were the only two errors. Working on the numerical results in response to the previous comment, now.  Comment By: Raymond Toy (rtoy) Date: 20090501 17:01 Message: I ran the entire testsuite using CMUCL 200904 on Mac OS X 10.5 with the current CVS code. I do not get any test failures either. Did you run the entire testsuite or just parts of it?  Comment By: Dieter Kaiser (crategus) Date: 20090501 14:36 Message: Hello Kenneth, I cannot verify the failures with GCL 2.6.8 and CLISP 2.44. There might be problem with the numericial calculations of expintegral_chi which is special to your Lisp implementation. For the problem 139 in rtest_expintegral.mac I get the following numerical results with CLISP 2.44: (%i12) z:0.5+%i; (%o12) %i + 0.5 (%i13) expintegral_chi(z); (%o13) 1.341686846905066 %i + 0.49714695079962 (%i14) conjugate(expintegral_chi(conjugate(z))); (%o14) 1.341686846905066 %i + 0.49714695079962 Internally, the following formula for the calculation is used: (%i20) 0.5*(expintegral_e(1,z)+expintegral_e(1,z)+log(z)log(z)); (%o20)  0.5 ( 2.683373693810132 %i  0.99429390159924) (%i21) expand(%); (%o21) 1.341686846905066 %i + 0.49714695079962 Can you post your numerical results.
