strftime: don't assume a byte count fits in 'int' * lib/strftime.c (add): Don't assume first arg fits in 'int'. I found this problem by static analysis, using gcc -Wstrict-overflow (GCC 4.5.2, x86-64). This reported an optimization that depended on an integer overflow having undefined behavior, but it turns out that the argument is a size, which might not fit in 'int' anyway, 2011-03-20 Paul Eggert <eggert@cs.ucla.edu>
