If the condition variable is const, the compilation successes.
Using built-in specs.

The problem also exists for 4.7.2, so no regression. The diagnostics is

[Bug 1172951] [NEW] gcc 4.7.3-1ubuntu10 c++11 bogus errors (reduced, not reproducible upstream)
Public bug reported:
This code:
namespace NS {
struct A
{
static void foo(int);
templatetypename Func
void func(Func f)
{
[](){
do {
do {
if (1)
foo(0);
} while(0);
} while (0);
};
}
};
}
void caller()
{
NS::A a;
a.func([]{});
}
Fails like this on Raring:
redeclaration_bug.cc: In instantiation of 'NS::A::func(Func) [with Func =
caller()::lambda()]::lambda()':
redeclaration_bug.cc:14:11: required from 'struct NS::A::func(Func) [with
Func = caller()::lambda()]::lambda()'
redeclaration_bug.cc:10:5: required from 'void NS::A::func(Func) [with Func =
caller()::lambda()]'
redeclaration_bug.cc:26:15: required from here

redeclaration_bug.cc:26:15: required from here
redeclaration_bug.cc:10:5: error: too many initializers for 'NS::A::func(Func)
[with Func = caller()::lambda()]::lambda()'
It compiles fine on Fedora 18's gcc 4.7.2 as well as a version of the
upstream 4.7 branch that I just built today. (The latter calls itself
4.7.4.)

I think this is c++/56388 upstream. r198010 on the 4.7 branch seems to fix it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1172951 Title: gcc 4.7.3-1ubuntu10 c++11 bogus errors (reduced, not reproducible upstream) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1172951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
