Summary0000023: conflict between tex.sprint and \input catcodes
DescriptionWith the lua code

  tex.sprint(<catcode table>, "\input x.tex ")

the first line of x.tex will also be read using <catcode table>.
Additional InformationThe problem here is that the internal variable that keeps track of "specialness" of the catcode table for lua-created input lines is cleared only at the end of the line, and that condition is not triggered by tex.sprint.

A quick and simple solution is not possible because a less obvious problem is that that "specialness" should really be part of the input_stack structure.
Otherwise in
   aa\directlua{tex.sprint(<catcode table>, "\input x.tex ")}bb

the catcode table will be reset before 'bb'.
TagsNo tags attached.
