Bug#881920: xerces-c: FTBFS on hurd-i386: ThreadTest15 failed

[Bill Blough]

After running the tests in a loop for many hours, I have encountered 2
issues.

The first is an assertion failure in ext2fs that causes the entire
system to freeze (#882507).  Based on the build log, this isn't the
issue in question, but it's definitely a problem (and it made
troubleshooting much more frustrating).

The second is an exception being thrown due to a call to getcwd()
failing.  I believe that this is the issue that caused the test failure
referenced in the build log.  However, getcwd is returning "No such file
or directory" but the directory clearly exists, and as such, I'm not sure how
this is happening.  I'm wondering if this is somehow related to the
ext2fs issues, or maybe load-related.

I've requested a binNMU for xerces-c on hurd to see what happens.

Given that the test explicitly involves threading, non-deterministic
behavior is well within the realm of possibility.  That said, tests
should of course consistently succeed.

Thanks!

That's very odd, as it built ok when it was uploaded to experimental, and the 
only change for unstable was the version bump.

I'll definitely look into it.

The latest build of xerces-c for hurd-i386 (admittedly not a release
architecture) failed, per the following excerpts from

The log doesn't give additional details, but perhaps you can reproduce
the problem on a porter box.

Could you please take a look?

Thanks!
