I could track the cause down to this commit in TexInfo:
https://lists.gnu.org/archive/html/texinfo-commits/2015-01/msg00074.html
There was an error in the global declarations of TexInfo, because one
hexcode has been used twice. Obviously the author thought it was a good
idea to detect this kind of trouble with additional checking and above
error message. However, this completely disables the possibility to
override declarations in the user space and breaks backward
compatibility of TexInfo documents.
I am going to file a bug report at TexInfo.
