[Bug libstdc++/21271] New: Invalid free in std::string

[chris at bubblescope dot net]

in Mac os x 10.3.9, I get warnings about "invalid or double free" from the following piece of code when 
compiled at at least -O1. I believe this code to be valid by the standard. Due to time constraints for a 
couple of weeks I'm not going to be able to investigate more carefully what is causing this problem, and 
in particular if it's libstdc++, g++ or the apple malloc checker's fault. Sorry.

#include <new>
#include <string>
#include <stdexcept>

void test01(void)
{
  int csz01;

  const char str_lit01[] = "rodeo beach, marin";
  std::string str01(str_lit01);
  csz01 = str01.size();
  std::string str03(str01,csz01);
}

int main()
{ 
  test01();
  return 0;
}

Hi Chris. Whereas I'm not seeing anything wrong with Valgrind on x86, I'm willing
to check also ppc-darwin but would appreciate detailed instructions to reproduce
the problem. In the meanwhile, I would suggest checking whether is an artifact
due to the pool allocation of mt_alloc: can you repeat your test with a GCC built
with --enable-libstdcxx-allocator=new?!?

Woops, false alarm, somehow I'd horribly, horribly messed up something. A clean OS reinstall seems to 
have cleared up this, and another unrelated problem. Sorry
