Description Michael Matz 2004-10-13 18:40:32 UTC
This came over from #17937.  The testcase 
#include <string> 
std::string idl_filename; 
extern std::string idl_filename; 
int main() 
        idl_filename = "bla"; 
        return 0; 
segfaults when compiled with "g++ -pthread test.cc". 
The reason is that there are two destroyer functions for "idl_filename" 
registered (__tcf_2 and __tcf_1).  This happens only if the "extern" 
declaration comes after the definition.

I filed one with a self contained example.
