Yes, valgrind is generally the first thing I'd try, but it has its own malloc
implementation and that changes what's happening.  If the rogue writes are
still happening, they're not happening in a way valgrind can detect.

It's also too slow to run the whole rebuild under.

I tried the debug mode of glibc's malloc and running that under gdb to find
the first problem it found, which was a call to free().  Checking the code
which lead to that point, all looks fine, so I think the heap has been
corrupted before then.

I was wondering what to try next - suggestions welcome.  Electric Fence was
what I was going to try next - I've never used it before, but it seems to use
mprotect to isolate heap allocations which seems promising.  The process
doesn't make a lot of allocations, so extra memory overhead shouldn't be an
issue.

Cheers,

System overloaded again?

Since yesterday, news.gmane.org often refuses connection, and new
articles are coming in slowly.  It looks like the system load is too
high once again. :-(

I was thinking that maybe Purify had a trial license, and I tried
clicking the "Trials and demos" link here:
 http://www-01.ibm.com/software/awdtools/purify/unix/

But the link didn't work, unfortuately.

Besides... I'm not sure if using purify is good form in the open source,
and volunteer community...?

Fortify Software has a project where they run their static analysis
software on open source projects:

Why is it hard to retroactively crosspost reported spam?

Why is it hard to retroactively crosspost reported spam to
gmane.spam.detected? 

Is this because it will be neccessary to write in the middle of large
NOV files, that normally only get appended to?  How large are these NOV
files anyway?  And how does INN know where a NOV entry start?  Do they
have a fixed size allocated for them?  Or is there an index on the side?
Or does it do a sequential seek always?

How large are the NOV files?  Are there any statistics?

Old FAQ (last updated 2004-04-09)

The FAQ was updated last on 2004-04-09, so there are probably some
things that are a bit dated in there.  The bandwidth and the "server
farm" comes to mind.

Or something.  Google needs to follow the pages to get the links to the
actual articles, but shouldn't really index them.  Is there a way to
specify that?

Not really, but it might happen at some point.

Perhaps the mailing list discarded the message?
