We ship linuxthreads' libpthread.a, but we don't ship nptl's libpthread.a. So, when you link statically with -lpthread, linuxthreads' libpthread.a is linked. We can export both nptl and linuxthreads libpthread.a like libpthread_nptl.a and libpthread_linuxthreads.a. But I think it's just debian's local hack - it may be ugly way. > But I noticed when doing ps ax that in the dynamic case I have a single > process with 9 threads and in the other case 9 process as if I was using > linuxthread. > > Is there anything special to do? Should I open a bug to libc6-dev Threads of linuxthread are appeared as multiple processes. nptl is the newer version than linuxthreads. nptl kernel hides such multiple threads, and threads are appeared as a single process when you execute ps command. However, note that kernel scheduler handles them as multiple processes like linuxthreads. It's appearance issue, and it's normal behavior.
