Why is svadev set to members-only posting?  I like the llvmdev policy better: anyone can post but replies only go to the list, so there is strong incentive to join the list if you want to ask questions.

The llvmdev and svadev configurations are the same (members-only posting).  If someone who is not subscribed to the list sends an email, a moderator needs to approve the message for delivery.  The moderator can opt to add the email to the "Accept filter" so that future messages from the same person do not require moderation.  Chris regularly adds people to the send filter; I typically do not unless the same person keeps posting over and over again without subscribing.

The Mailman software does not really support the model that Chris wants (which is to have the first post moderated and subsequent posts automatically accepted for delivery).

As for where replies go, the only thing the mailing list software configures is what the default email address should be when you hit the "reply-to" button on your mail reader.  I can change svadev to do what llvmdev does in this regard if that is what you want.

Hi,

I'm using CentOS 6.3, clang version 3.2  with latest ld checked out from cvs
I followed instructions on wiki and installed clang with lto (gold plugin)

I'm having troubles compiling this simple program:

#include<string>
#include<map>
#include<iostream>

using namespace std;
int main(int argc,char** argv){
   map<string,int> themap;
   string test(argv[0]);

   themap["key1"]=1;
   cout << test << endl;

   return 0;
}

clang++ -g  -O2 -flto -use-gold-plugin -fmemsafety  -o main main.cc  -L /opt/SAFECode/lib

FIXME: Ignoring global of size zero: @_ZNSs4_Rep20_S_empty_rep_storageE = external global [0 x i64]
lto-llvm.o-O8q9Q2:ld-temp.o:TargetList: error: undefined reference to 'std::string::_S_compare(unsigned long, unsigned long)'
lto-llvm.o-O8q9Q2:ld-temp.o:TargetList1: error: undefined reference to 'std::string::_S_compare(unsigned long, unsigned long)'

If I remove -O2 option it links fine.
What's strange if you comment  out line:  themap["key1"]=1; it will compile.
What even more strange :-) if you comment out:  cout << test << endl; instead it will also compile any ideas ?
Is this bug in clang ld or libstdc++ on centos 6.3 or combination of all.

Thanks
Krzysztof
