Thanks for tracking this one down.  I usually only run "./check-guile
srfi-18.test"; I never looked seriously into this file.  There's a bit
of a mess here and elsewhere in the test suite about modules and paths,
but I did add a comment.

FYI in the upcoming Guile 2.2 (and already in the prereleases),
thread-terminate! should be much more reliable.

    Does anyone know how to convert the srfi-18.test test case into a
standalone one that can be debugged in lldb or gdb? On darwin15, I
have confirmed that the thread-local-storage support is causing the
failures of...

 FAIL: srfi-18.test: thread-terminate!: termination destroys non-started thread
 FAIL: srfi-18.test: thread-terminate!: termination destroys started thread

and that passing configure 'ac_cv_have_thread_storage_class=no' to
configure when building guile 2.0.12 suppresses these failures.
   I've opened a radar bug report with Apple, radar:// 2868809 "guile
2.0.12 exposes potential thread-local-storage bug on Mac OS X", but
still need to add a stand-alone test case derived from srfi-18.test
that can be debugged in lldb.
            Jack
