Subject: [Bug c++/56611] New: [C++11] Template instanciation failure with variadic arguments and template aliases
Date: Wed, 13 Mar 2013 10:24:00 -0000 [thread overview]
Message-ID: <bug-56611-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56611
Bug #: 56611
Summary: [C++11] Template instanciation failure with variadic
arguments and template aliases
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: antoinep92@gmail.com
The attached code fails to compile because of failed template instanciation /
type matching, but seems correct, compiles with clang, and can be made to
compile with gcc with minor modifications (see code comments).
Problem statement:
R<Func(int, int)> need result2<int, int> but the compiler does not seem able to
instanciate result2<int, int>. If result2<int, int> is explicitly instanciated,
the code compiles. Also if template alias result2 is replaced with a typedef in
a class (result1) the code compiles.
