Having carefully investigated Versions 2.2, 3.0, 4.0, and 4.1
I came to the conclusion that many problems propagate along
several versions. Also, rather often they disappear, and then
resurface.
Might it help to the developers to fix the bug (or to help them
in any other way) if I would also name the concrete version where
the bug appeared for the first time? Save them some time?
Say, kinda the following:
...............................................................................
BUG # 101 Integrate: INVALID PAGE FAULT/0167:64607028 BuildNumber=156656
Bug Presence Table:
YES 4.1 for Microsoft Windows (November 2, 2000)
YES 4.0 for Microsoft Windows (April 21, 1999)
YES Microsoft Windows 3.0 (April 25, 1997)
NO Windows 387 2.2 (April 9, 1993)
BuildNumber 156656
CPU ID AuthenticAMD AMD Athlon(tm) XP 1600+
RAM size 512 Mb
Free HDD size 11 Gb
OS ID Microsoft Windows 98 4.10.2222 A
After about 2 seconds while Mathematica 4.1 is the single running task
MATHKERNEL caused an invalid page fault in module MATHDLL.DLL at 0167:64607028
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(1/3)), {z, 0, 1}]
The same problem with
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(1/4)), {z, 0, 1}]
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(1/5)), {z, 0, 1}]
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(-1/3)), {z, 0, 1}]
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(-1/4)), {z, 0, 1}]
Integrate[(Sqrt[1 + z^3] Log[z])/(1 - (-z)^(-1/5)), {z, 0, 1}]
..............................................................................
Or, to name the versions is not very helpful?
(Actually, this version localization might take a tangible amount of time.)
