I have a probably related problem. Sporadically, an attempt to do

a[,1,1,drop=F]

or similar subsetting on a 3-d matrix causes a segfault at line 83 of
attrib.c.  In a previous version this happened reliably when dimensions
were lost from multi-d arrays and was due to incorrect handling of the
dimnames attributes which crashed attrib.c at that point when the dimnames
were accessed.

Is the same sort of thing happening again?
