pinot-dbus-daemon segfaulting after short time of indexing

[GoogleCodeExporter]

I am using pinot 1.0 on an ArchLinux 64bit box. 

When pinot-dbus-daemon is started, it begins to index files (I guess from the 
CPU usage) and after like 20 seconds, it segfaults. For an strace of this case 
see pinot-dbus-daemon.strace.

I thought it might be a problem with my pinot config, so I deleted ~/.pinot and 
configured pinot (using pinot-prefs) to scan my home folder (/home/martin). 
Restarting pinot-dbus-daemon, it segfaulted again after some seconds (see 
pinot-dbus-daemon.new.strace).

After a downgrade to pinot 0.98, the dbus-daemon seems to not crash anymore 
(even with the old config in place).

The attached file pinot-deps-versions contains all dependencies of pinot with 
their installed version.

Thanks for the bug report.
Would you be able to compile in debug mode (./configure --enable-debug=yes 
...), reinstall and attach gdb to the daemon until it crashes ? We could then 
get a backtrace with gdb's "thread apply all bt" command.

I've just noticed that v1.01 is already released and tried it. But the result 
stayed the same. I've also done a backtrace (which looks quite similar I guess).

What version of boost do you have ?
Could you try rebuilding with "./configure ... --enable-mempool=no" ?

I've got boost 1.50.0.

The mempool option seems to have done the trick. At least pinot-dbus-daemon 
does not crash after creating the 3rd thread anymore. I'll have pinot index my 
files and report if it segfaulted again.

Looks good so far. No crash in the last 30 minutes indexing. Should I suggest 
the ArchLinux pacakage maintainer adding --enable-mempool=no ?

Yes, good idea. With boost >= 1.48, that's what I would recommend.
