Looks like *many* years. I get the wrong output with texlive 2012.

It looks like a problem with \cr for me, but it is difficult to be
sure.

This sounds like a bug. Offhand, I don't know what changed to cause 
this, but it probably shouldn't have!


Filing an issue at https://sourceforge.net/projects/xetex/ would be 
useful, to help us keep track.

It would be useful for me to know which of \ifcat, \relax, and \cr
changed, to determine whether I should just special-case \cr in my
package, or use some other tool than \ifcat.

Best regards,

[XeTeX] ifcat changed?
