"It worked for me." It was a long time ago, though, on a system far, far away.
Are you sure you're setting the correct registry entry? I noticed that in

Is this a bug or simply an unimplemented feature? Is it a limitation

manager or something?)
Ive seen plenty of mails regarding this and this is the only solution listed

putting the registry key in the right place and everything, I've even logged
in as administrator and made sure the key is set in that environment too.
Has anyone allocated more than 256 megs in a cygwin compiled app?
