2.8.7 crashes immediately after launch

[pstrg]

If I try to launch mlnet.exe (2.8.7) directly, it immediately crashes.

Error report window shows
mlnet.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Error signature
AppName: mlnet.exe AppVer: 2.8.7.0 ModName: mlnet.exe
ModVer: 2.8.7.0 Offset: 002f6850

With 2.8.6, exactly the same happens; offset is 002f64d0


Incidentally, if I try to launch using sancho, besides the error report window, the Core DOS window shows
availableProcessors: 1
maximumMem: 9223372036854775807
totalMem: 3608576
freeMem: 1245184

and the Core not found window shows
127.0.0.1:4001 does not accept connections (core not found), try again?

Which Windows version do you use?
Did you disable any firewall/antivirus software to see if it interferes?

Windows XP Pro SP2, fully updated.
Set exception for mlnet.exe on
- Windows Firewall and
- NOD32 IMON (as directed on "Windows specific annoyances").

Disabling Windows Firewall and IMON has no effect on the problem - report error message is the same as before.

CPU? Do you use DES or similar security related features?
I never saw such an error myself and you are the first one to report it.

CPU is a 800 MHz Via C3 (the machine is a very small one I maintain always on as file server) with 256 M memory.
No DES.

Do you think the problem may be CPU-related?
Is there any test I could perform to be sure?
Until now no problem with other software has been observed with that machine.

I must add that I just tried mlnet on another machine and it behaved well.

[spiralvoice]

If you got mlnet.exe from http://sourceforge.net/projects/mldonkey its compiled for i686.

According to http://de.wikipedia.org/wiki/VIA_C3 (german) a 800MHz Via C3
CPU can only be the Ezra or Ezra-T which are, unlike their successor
Nehemiah(+), not i686-compatible because they lack the cmov command.

Here are more details about it:

I will try to compile mlnet.exe for i586 and will drop a note here when ready.

Good!
The lack of the cmov instruction is most certainly the cause of the problem; I was not aware of that until now.
The i586 compile may be of use to others too.

[spiralvoice]

Well, it took me a while to setup a 586 build environment, but I took the time
to update to Windows build guide as well:
http://mldonkey.sourceforge.net/Windows#MinGW_Installation

Hopefully this binary will work on your machine, its todays CVS checkout:

[pstrg]

Indeed it works!
Thank you very much for your time and dedication.

[spiralvoice]

Ok, future binary versions on sf.net will be compiled in the new i586 environment.

IMHO using MLDonkey on Windows with i386 or i486 CPUs does not make sense.
