Bug ID: 66333
Summary: [C++14] Static constexpr template
Product: gcc
Version: 5.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cypherpu at gmail dot com
Target Milestone: ---
Created attachment 35650
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35650&action=edit
line colTest2 fails, line colTest4 succeeds
In the attached file, line colTest2 fails with:
gcc_constexpr_bug.cpp:36:99: error: ‘ColumnObject<Staff,
std::basic_string<char> >{&Staff::nickname_, ((const char*)"nick_name")}’ is
not a constant expression
static constexpr auto colTest2=ColumnObject<Staff, std::string
>(&Staff::nickname_,"nick_name");
Note that std::basic_string is only used in the declaration of a member
pointer. Also note that although this line fails, a very similar line succeeds
(colTest4 in main()).
[]$ gcc -v
Using built-in specs.
