[Sbcl-devel] NUMERIC-TYPE-HASH-MIXER failures

[Stas Boukarev]

Getting frequent random

::: Running :NUMERIC-TYPE-HASH-MIXER
::: UNEXPECTED-FAILURE :NUMERIC-TYPE-HASH-MIXER due to SIMPLE-ERROR:
        "The assertion (<= PRE 7) failed with PRE = 8."

[Douglas Katzman via Sbcl-devel]

I pushed a change to help diagnose this since I'm not getting anywhere near that high a value for PRE implying poor hash mixing.

Please mail the complete output of that test from a failing run when you get one. Something like:

::: Running :NUMERIC-TYPE-HASH-MIXER
Dumping SB-KERNEL::*NUMERIC-TYPE-HASHSET*
Mask=3FF, maxPSL=4
(0)                                           (INTEGER -4611686018427387905 -2)
(8)                                           (INTEGER * 0)
(8 9)                                         (INTEGER -173 104)
(11)                                          (DOUBLE-FLOAT * 1000000.0d0)
