[Bug c++/34297] New: static linking with pthreads stl runtime error

[thehighhat at gmail dot com]

Tracking down a problem with a much more rigorous codebase.  Using this
contrived example to demonstrate the issue:


#include <iostream>

using namespace std;

// static link this with pthreads to test

int main()
{
  // this will exit cleanly
  cout << "std::cout" << endl;

  // this will segfault, why?
  cerr << "std::cerr" << endl;

  return 0;
}



On default setup of RHEL 4, 32bit host and compiler, compile as:

g++ test.C

works fine.  Then statically link:

g++ -static test.C

works fine.  Now use -pthread option:

g++ -pthread test.C

works fine.  Then statically link:

g++ -static -pthread test.C

problem!   The compile and link are both successful.  However, when executing
the code, it segfaults.

This does *not* happen on 64bit host and 64bit compiler.

It does happen on 64bit host and 32bit compile (-m32 option).

Note that std::cout does *not* cause segfault, but std::cerr does.

This happens also with g++ 4.1.1 on RHEL4, again in 32bit.



Also, using Intel compilers 9.1 version shows the exact same pathology. 
Example

  icpc -static -pthread test.C


----------

I cannot determine the cause, nor can I find a workaround. 

Perhaps there is an issue with the STL in 32bit in GCC?
