command folders prints a bad list (more info)

In fact, if I compare the result of :
find <my MH directory> -type d -print

and the result of :
folders -recurse

it's the last printed name that isn't included with the "folders" command. 
With MH 6.8.3, the result is good. I supposed there is a count error in 
iup/folder.c, but I don't found it yet.
