I have 4 GB of ram, and a 4 GB page file (pagefile.sys).  How big is your
page file?

(Unless by "page size" you mean something other than the size bo
pagefile.sys.)

I suppose I could reboot and try to kill off any unnecessary processes,
and try the build again, but doing so would be enough of a nuisance that
I'd prefer not to do so if it's just a shot in the dark.

Ah, that's interesting.  I suppose I could just build the release.

But -- and correct me if I'm wrong -- isn't it the case that if I want to build
*my* code in debug mode (which, sadly, I sometimes want to do) , I have
to build it against debug version of Qt?

Thanks for your help.
