Invalid realloc size of 0 when installing on an AMD athlonXP barton powered machine

[Baldur Gislason]

I'm trying to install 5.2.1-rel from FTP with an intel 100Mb network card on 
an AMD AthlonXP barton 2500+ with an Aopen AK77-8XN motherboard and 1GB ram. 
When at 65% through extracting base, sysinstall crashes with the message:
Fatal error: Invalid realloc size of 0! - PRESS ANY KEY TO REBOOT
I know this is a very common problem these days, has any solution been found? 
I'd rather sell this machine than using some other operating system on it.
