This is a bug.
Can you open a bug request for this please.
Do you use the id tag ? (references) in macro definitions.
The way references work at the moment could (I think)
cause the symtoms you describe.
see: http://issues.apache.org/bugzilla/show_bug.cgi?id=34458
for an example.
Please try to get a small build file/s that shows the problem.
