Adhemerval Zanella 320ac7eeb4 vfscanf-internal: Remove potentially unbounded allocas
Some locales define a list of mapping pairs of alternate digits and
separators for input digits (to_inpunct).  This require the scanf
to create a list of all possible inputs for the optional type
modifier 'I'.

Checked on x86_64-linux-gnu.
