I hope this helps.

Interesting. Now, can that be considered a "bug" or a "feature" of
glm? My own oglm and gologit2 programs give these phenomenally high
standard errors when you have perfect outcome predictors, mostly
because I've never figured out how to trap such situations and issue
a warning or error message.
