 So I played with the pkgsrc-wip ecl stub to upgrade it and test 9.6.0
 (which actually has first-level directory ecl-9.6.1), and unfortunately
 ecl_min also has the same endless loop problem after various SIGSEGV.
 I here include the result of ktrace on it:

 The next steps would probably be to attempt to debug ecl itself
 building ecl_min with -g and debugging it with gdb and read its
 sources, but I will probably be unable to investigate further until the
 beginning of the next week.
 
 I also tried to subscribe to the ecl mailing list as well although the
 confirmation message is still pending  because of sourceforge
 greylisting.  Not exactly about this problem, but because I noticed
 that the threading code does not detach created threads while also not
 joining them, when one of the two must be done according to POSIX
 (implementations are free to leave resources pending until the thread
 is joined, like its return code, possibly even its whole stack, unless
 the threads are started in detached mode).  So three is a problem there
 already, including in the latest release.
 
 If you're also subscribed there and the bug really is an ECL one, we
 could resume further technical discussion there as well, until we get a
 working ECL to update this PR with the news.  If this can't be resolved
 in a reasonable time frame, it might be best to fix -current and
 pkgsrc-2009Q1 boehm-gc and ecl as per the first message, potentially
 making thread support a pkgsrc option as well...  I also could provide
 an additional diff so created threads are detached in 8.12.0.  I'll
 also forward it upstream via the mailing list once I'm subscribed
 (although against their CVS HEAD).
