Hi Dirk

r-bioc-biocgenerics, r-bioc-s4vectors and r-bioc-iranges all got 
workarounds for this and autopkgtests are passing again [1][2].

The regression was fixed in R-3-4-branch r73465.  I have no idea if 
anything else in the archive is affected as not all packages have 
working autopkgtests.  Would you please consider uploading 'R 3.4.2 
Patched' from svn >= r73465?  r73475 includes a test.

Regards
Graham
