Yes, it does. Not on all platforms, but on amd64, for example. Passing va_list as an argument does not make a sufficiently deep copy, so that va_arg in the callee affects subsequent va_arg invocations in the caller. > Does this break C89 and C90? Some systems have got __va_copy. There's probably an autoconf test for this. -- Florian Weimer <fwei...@bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99 -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of "unsubscribe".
