Re: [Boost-users] What's wrong with this simple multithreaded function that uses regex?

They lie :) Seriously though, have hit this problem at various times, definitely with more recent versions of gcc than 4.0.4 on Linux x86 32-bit and 64-bit; suppose I might need to chase this one down more thoroughly at some point. On Thu, Aug 4, 2011 at 2:39 AM, wrote:

I'm guessing that is dependent on the version of gcc; I've hit this problem with gcc on Linux, on various versions up to and including gcc 4.1.something. Do you know when specifically this was fixed in gcc?

Its a gcc feature, not something to be fixed ;) I found in http://gcc.gnu.org/gcc-4.0/changes.html, which describes new changes for gcc 4.0.4: "The compiler now uses the library interface specified by the C++ ABI for thread-safe initialization of function-scope static variables." Apparently the support is already in 4.0.4, earlier it might be there as well, but maybe in some unsatisfying way.
