Possibility of patching 2.0.5 for armhf support

Possibility of patching 2.0.5 for armhf support

[Rob Browning]

I've had a request for armhf support in wheezy (which has 2.0.5), so I
thought I'd ask if you might know offhand what fixed the armhf build in
more recent versions (assuming it was a code change and not something
else like the build toolchain).

For example, 2.0.11 works fine there, but 2.0.5 dies like this:

  https://buildd.debian.org/status/fetch.php?pkg=guile-2.0&arch=armhf&ver=2.0.5%2B1-3&stamp=1332497200

(...segmentation faults in 3 of the tests.)

While I probably can't put 2.0.11 in wheezy (stable), I might be able to
add a suitable patch to 2.0.5 -- assuming it doesn't require major
changes.

Thanks

I suspect the main difference is the libgc version, no?  That
test-pthread-create-secondary was skipped indicate that
libgc < 7.2alpha5 was being used here, which may explain the
other problems.

That said, there have been many changes both in Guile and in libgc over
the last 2.5 years.
