rpmbuild ignores /var/tmp being full?

[Peter Chen <petechen netilla com>]

Hi,

With RPM 4.0.3, I witnessed a few cases when /var/tmp is full, rpmbuild
simply ignores it.  Is this a bug?

Specifically, during %prep, %build, /var/tmp/rpm-tmp.* shell scripts
generated were empty when /var/tmp is full.  Is there some way to trap
these write failures, so rpmbuild will bail out with an error instead of
continueing?
