Yes, this is what I have observed. I do not get crashes but since our MED files are 78 columns (for reasons not relevant to this discussion), our splitting apart approach has worked well. Carlo On Mon, 6 Oct 2003, Matt Newville wrote:

Athena does not handle that many columns gracefully. We use a Python program to split these data up into one file for each of the elements and then work from there.
Oops, I was wrong earlier. In fact, I usually use ifeffit to read files with many columns or beamline-specific software to add columns together. But the file at http://cars9.uchicago.edu/ifeffit/contrib/MED_FILES/mn_x.001
is an example of a multi-element detector file that can be read directly with ifeffit. It has 56 columns, and lines that are 830+ characters long. Ifeffit can see all columns with read_data(mn_x.001, group=mn)
The file http://cars9.uchicago.edu/ifeffit/contrib/MED_FILES/x.001
is not EXAFS data, but has 73 columns, and lines with 1090+ characters. Ifeffit reads it fine.
But, Carlo is right: athena does not handle that many columns. In fact, it shows "only" the first 35 in its data-column interface for these files, though the file viewer shows the full line length. I suspect that Bruce never noticed this.
I don't know if that was the original problem, but I thought I'd try to clear up the confusion.
