Hi there,

I'm running a build of 6fc3eae477 on debian stable:

% ./config.status --config

`libgc' is version 7.1 built from source and installed to `/usr/local'.

Okay now that we got that out of the way, the tests that hang for me
are:

  + test-pthread-create
  + test-fast-slot-ref

The former does react to sending a sigint by hitting C-c. The latter
appears to not care about that. Sending sigterm via kill to both does do
the job, though.

Andy Wingo asked me to attach gdb and get a back-trace, so here they
are:

For `test-fast-slot-ref':

Thanks for the detailed report.

I have fixed these hangs in master.  With libgc 7.1, GC_do_blocking
doesn't exist, so libgc needs to be able to stop the signal delivery
thread, so we need to unmask the suspend signal there.  With that fix in
place things work again.

However, the main test suite now segfaults with libgc 7.1.  I'm not sure
why.  I am appending a representative backtrace.  It seems to be some
sort of corruption of the allocator's data structures.  It could be a
Guile problem, or it could be a bug in libgc.

Things do appear to work correctly with libgc 7.2alpha5 (or CVS).
Perhaps given that master has moved away from pthread redirection, we
should simply require libgc 7.2 for Guile 2.2.

Yes, absolutely.  Speaking as a user :-), I would not mind at all being
told "you must use version X.Y of libgc because it's the only one we
support".  Based on the number and complexity of GC-related issues over
the last few months, and the level on continuing change in libgc, I
think it could be a fruitless and losing battle to try to support
multiple libgc versions - and at the very least it's a lot of extra
effort.

(And IMO it's also fine for you to arbitrarily advance the X.Y, when
there's a new libgc release with a fix or feature that Guile needs.)

Regards,
        Neil
