When printf is running builtin in a sh, global vars aren't reset to 0 between invocations. This affects "rval" which remembers state from a previous %b \c and thereafter always exits after the first format conversion, until we get a conversion that generates an error (which resets the flag almost by accident) printf %b abc\\c abc (no \n) printf %s%s hello world hello (no \n, of course, no world ...) printf %s%s hello world hello printf %s%s hello world hello printf %d hello printf: hello: expected numeric value 0 (no \n) printf %s%s hello world helloworld (no \n, and we are back!) This affects both /bin/sh and /bin/csh (and has for a very long time). XXX pullup -8 |
