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.) Vladimir Bondarenko
