psql.exe execution error - Mailing list pgsql-general

I work on Windows 2000. I start psql.exe on a console. The PostgreSQL
Interactive Terminal seems to run well.
But each time I execute a commande like \d or \l or anything else, I
quit psql and I get the following error :
the "0x77fc9e82" instruction uses "0x00000000" memory address. the
memory can not be written.

Does anyone can send me the psql.exe file that works fine on Windows
2000 ?

thanks for help
