Hi list,
I never received any reply to this, so I assumed nobody already knows this bug. I have therefore reported it at <http://subversion.tigris.org/issues/show_bug.cgi?id=3670>.

I know this is a local problem on my machine, I already drew that conclusion, however...

It was actually a problem with the APR library, but it was quite weird. After I recompiled the exact same version of the APR library -including packaging revision, so *no* changes to the one I had-, installed that version, then recompiled SVN and ran the test case, it worked fine. At least, I'm at 42/71 and there are no errors yet. Maybe it has to do with APR not being updated for a long time, so I compiled SVN with another compiler version than APR, or something like that.
Either way, test suite succeeds after recompilation of APR then SVN. I'll update the bug report. Thanks!

Packaging is very complicated because it involves linking
Subversion to the right libraries at build and run-time.
It is easy to overlook subtle problems during build and installation
which cause unexpected behaviour (such as random segfaults).

If other fink users don't see it, that makes it even more
likely that you have a local problem on your machine.

I did check the bug report.
The paste-bin post linked from the bug report (http://pastebin.com/RmFVqZYd)
contains obvious failures such as:
sjors@smbp:~/Projecten/ruwave/svn/trunk/server$ svn status
Bus error
sjors@smbp:~/Projecten/ruwave/svn/trunk/server$ svn up
Segmentation fault
This means something is broken with the Subversion build and/or
installation. Most likely a problem with incompatible APR versions
being used at build time and at run time.
Subversion developers are running the test suite on MacOSX before
release. And we don't release with failing tests.

You mean the hypothetical off-by-one bug you mentioned?
Or this trace?
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
0x0010108a in svn_io_get_dirents2 ()

(gdb) quit
This is very likely a problem with the APR library, because it is
used to do i/o. If Subversion cannot even read dirents, I'm wondering
why any of the regression tests pass for you at all (maybe it works
half the time?).
I'd like to help you figure out what the problem is.
For starters, let's find out what APR your Subversion binary runs with.
Please post the output of:
ldd `which svn`
Thanks,
Stefan

Hello Stefan,
As said in the original message, I did talk to the Fink package maintainers, which recommended me to run the test suite, which failed. A test suite does not normally fail because of a simple packaging problem.
Fink patches the libtool file to fix compilation, and it uses extensive configure flags. None of this should make so much of the test suite fail, let alone corrupt repositories. None of this has been changed, as far as I know, in the past versions; this bug also does not appear with some of the other SVN users on Fink I've spoken to.
Please check the bug report itself, it contains some more information, including a lead on what might be the cause... :)
Thanks,
Sjors

The Subversion project itself does not maintain the Fink package.
So I'm afraid we're probably not the right people to file this issue with.
I suspect an error in the packaging, rather than a bug in Subversion.
Please talk to the Fink package maintainers.
Thanks,
Stefan
