Release Status: release

Description:
        printf.def:printstr will skip output if *string == '\0' but
        that is valid data for printf %b "\0000"        

Repeat-By:
        /usr/bin/printf %b "\0000" | wc -c
        1
        bash -c 'printf %b "\0000"' | wc -c
        0
        after fix wc sees 1 byte of input

Fix:
