Comment (by javran):

 Replying to [comment:13 bherzog]:
 > The test-cases are a bit too fragile. All three of the
 `T9579_stackoverflow_*` tests fail for me because of differences in the
 reported stack size:

 I'll try to fix this, what I have in mind is to pipe stderr to replace the
 actual number with a constant string, as the actual number is not
 important for testing this.

 Any ideas?
