I compared the control files and file lists from the packages and marked the 
build "broken" if it found significant differences.  So that would have 
caught the case above.  But not a case where, for example, the compiler runs 
were started before patches were completely applied, probably resulting in a 
mix of patched and non-patched code.

However, due to the issues raised in the previous thread about 100% bit-by-bit 
reproducibility of package builds, I don't see any good way to detect that 
case automatically.
