Bug ID: 80122
Summary: __builtin_va_arg_pack() and
__builtin_va_arg_pack_len() does not work correctly
Product: gcc
Version: 4.8.5
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: rpirrera at aitek dot it

test __builtin_va_arg_pack()
__builtin_va_arg_pack() has changed behavior from version 4.4.7.
In case of only an always inline function all work correctly but if the always
inline function passes the __builtin_va_arg_pack() to another always inline
function the computed __builtin_va_arg_pack_len() is 0 instead of the number of
variable arguments.
In attachment you will find a test program reproducing the issue.
