I would like to have a look at the app.

Subject: [ntdev] [OT?] Found bug in Windows 2000 registry code
Hi all. Yep, it’s me, Hyperion, again, with my darn POSIX subsystem again
Don’t worry, today I’m not here to bore you with my sloppy, buggy code. The
plat du jour, this time, is something hot: uname(), that exposes some weird
kind of bug in the Windows 2000 registry
uname() uses native registry functions to read the computer name from
registry (key
“\REGISTRY\MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveCompu
terName”,
value “ComputerName”). When my test app is run in a debugger (Dependency
Walker’s profiler, specifically - I haven’t tried others, Windows 2000
boots too slow to do this kind of tests), uname() BSODs the machine with
the following error:
STOP: 0x00000051 ( 0x0000000C, 0xC0000005, 0xBE2EDB78, 0xBE2ED70 )
REGISTRY_ERROR
This isn’t an ordinary bugcheck. This is some serious crash: the kernel
doesn’t even create the memory dump. I can’t run a kernel debugger either,
as I can afford neither a second machine nor SoftIce. I hope that all those
funny numbers have some meaning
(BTW: when it’s run normally the app crashes with a non-continuable
exception. Specifically: an access violation, instruction 0x784ABAAC,
address 0xFFFFFFFD, read attempt. So, yes, my uname() has some bug, but,
hey, an user-mode app crashing the kernel is called “operating system bug”
in my book. Anyway, how am I supposed to know where the bug is, if when run
in a debugger my app crashes the system?
Now, what should I do? how do I file a bug report to Microsoft? What
information should I provide, and, more important, to what e-mail address?
And do you think it’s worth? are they known for giving constructive replies
to bug reports?
PS: I can send to the brave souls that wish to test this by themselves my
test app and psxdll.dll
