Interesting example of concurrent modification. By default, find does
recursion breadth-first - it builds the list of all candidates in the
current directory, then tries to descend into that list. But you
deleted a in between those two steps.
You will not get the error if you tell find to do a depth-first search:
find . -depth -name a -exec rm -rf {} \;
For that matter, maybe you would be more interested in directly using
find's -delete action, rather than exec'ing external processes - this is
more efficient:
find \( -name a -o -path '*/a/*' \) -delete
