makeinfo segfaults with @itemize line with @item on the same line

[Dumas Patrice]

Hi,

I triggered makeinfo from texinfo-4.5 to segfault with the following 
construct:

@itemize @bullet @item on the same line that itemize
@item more text 
@end itemize

Here is the output (... means repeated, up to a large number):

$ LANG=C;makeinfo bug_makeinfo.texi
bug_makeinfo.texi:24: @bullet expected `{...}'.
...
Too many errors!  Gave up.
...
Segmentation fault

I tried to do a bt, but it is too long. There must be some recursion error.
I give the beginning of the bt, though:

(gdb) run
........

I attach the .texi file.
