Extended Description

Hello,

I am using a snapshot of llvm+clang from yesterday, with the headers of libstdc++-4.2, on debian testing x64. When I compile and run this code:

#include
int main(){
throw std::logic_error("Hello.\nAgain?\n");
return 0;
}

with g++ I get this output:
terminate called after throwing an instance of 'std::logic_error'
what(): Hello.
Again?

with clang++ -O2 I just get a segmentation fault. Without -O2, I get "terminate called without an active exception" before the segfault.

I can confirm this error on Ubuntu 10.10 using:

$ clang++ -v
clang version 2.9 (trunk 125563)
Target: i386-pc-linux-gnu
Thread model: posix

$ ./test
terminate called without an active exception
Abort

Please try this again with a ToT clang (or wait for 3.0); there have been major improvements in this area within the last few months.

Confirmed. Using a recent of clang the output is the same as for gcc:

clang++ -v
clang version 3.0 (trunk 138731)
Target: x86_64-unknown-linux-gnu
Thread model: posix

lsb_release -d
Description: Ubuntu 11.04

./test
terminate called after throwing an instance of 'std::logic_error'
what(): Hello.
Again?

Abort
