Re: 1.8 make check failing in popen.test

I have some further information, and it's quite surprising.

At this point with a fresh guile-1.8.0 tree, popen.test no longer
fails during make check, it hangs, but only in *some* trees.  If the
tree is named guile-1.8.0, the test will work.  If the tree is named
foo-1.8.0, the test will hang.


For example, if I do this:

   tar xzf guile-1.8.0.tar.gz
   cd guile-1.8.0
   ./configure --host=i486-linux-gnu --build=i486-linux-gnu --with-threads=yes
   make
   make check

popen.test doesn't hang, but if I do this

   tar xzf guile-1.8.0.tar.gz
   mv guile-1.8.0 foo-1.8.0
   cd foo-1.8.0
   ./configure --host=i486-linux-gnu --build=i486-linux-gnu --with-threads=yes
   make
   make check

it does hang (repeatably).

I've looked at the process in gdb after it hangs, and it appears to be
blocked in a select waiting in (I think) the "no duplicate" test.

At first I thought this might just be a local issue, but then I asked
someone on irc to try the same thing, and they saw identical behavior
on a completely different architecture (powerpc).

I'd really like to get this tracked down.  The reason I noticed the
problem is because the tree that the build tree for the forthcoming
Debian Guile 1.8 packages isn't named guile-1.8.0.
