Re: [Kaldi-users] Crashes with multiple threads

[Daniel P. <dp...@gm...>]

Ricky, I don't know if you have time to deal with this?  I know you've
dealt with the patching of OpenFst before.  This code could be put inside
an #ifdef so it will only be active if it's being compiled with gcc version
>= 4.1. (There's something like _GXX_VER or something like that, I think).
 The patch should contain a comment saying it is a patch applied by the
Makefile in kaldi's tools/ directory, so that if someone has compilation
problems they will know where to look.

Dan

  //int Incr() const { return ++count_; }
  //int Decr() const {  return --count_; }

    int Incr() const { return __sync_add_and_fetch(&count_, 1); }

  int Decr() const { return __sync_sub_and_fetch(&count_, 1); }
