As far as I know, the version of tcl bundled with MacPorts is stock, with no modifications.

You should report the bug to the developers of Tcl, because you are the one experiencing the problem.

  • Ticket #49160 – Description

    initial v2  
    55That appears to be because of the test for the availability of the pthread*_np functions succeeds because the link-optimiser suppresses the actual symbol tested for from the test app. Looking at the test code this appears to be something any good optimiser would (or could) do; after cleanup the test "payload" looks like this:
    66
     7{{{
    78main()
    89{
    … …  
    1112        return f != pthread_getattr_np;
    1213}
     14}}}
    1315
    1416In other words, the main function should always return true, the actual value of the variable (including "undefined") is moot for the test result.
