Hi,
I got a stack overflow error when training a glm model with a very long
formula.
I just tried with a formula of length 1000. How long was yours?
Which version of R? Where is the repdroducible example?
We have a glm formula with 76251 terms, the text of the formula is about
150K, we are using R 2.14.2

You would need do compile your own copy of R and increase the stack
size, on the slow machines around here, it takes even hours just to
parse the formula.
Aynway, I canmnot believe you have a sufficient number of observations
in the end:
You need at least 76252 obs and that means the design matrix needs > 46
Gbyte! Hence a sensible calculation is not really possible unless you
have really big machines around.
Best,
