[Bug-gnulib] Problem in gnulib's vasnprintf.c with formats like "%2.f"

[Tor Lillqvist]

Hi,

There seems to be a problem in gnulib's vasnprintf.c. If you pass it a
format like %2.f (with the period that introduces the precision, but
with an empty digit string for the precision), it crashes.

(I haven't verified this with a current vasnprintf.c from you, but
from looking at the code through savannah's CVS web interface, the
same problem seems to be present.)

See http://bugzilla.gnome.org/show_bug.cgi?id=142400 , especially from
comment #2 onwards.

Cheers,
