Crash on loading a specific wav file

[Phlogistique]

I got a crash with the current trunk by loading the attached file in Mixxx. I'm attaching two logs as a follow up.

Mixxx compiled under Arch Linux with "scons prefix=$HOME tuned=1 qtdir=/usr/share/qt"

Hi Phlogistique,

Is this 100% reproducible by you? Could you please get us a backtrace for this? See http://mixxx.org/wiki/doku.php/creating_backtraces

That will help nail down which part of Mixxx is crashing.

Thanks,
RJ

Also, what version of libsndfile do you have built?

[RJ Skerry-Ryan (rryan)]

Hi Phlogistique,

Could you please check what version of libsndfile you have built? We're in the process of releasing Mixxx 1.9.2 this weekend and we'd love to get to the bottom of this before we release it.

Thanks,
RJ

Here is the backtrace with 1.10:

I don't think I can reproduce with 1.9. I'll check that right now.

Reproduced with 1.9;

libsndfile is libsndfile 1.0.25-1 installed from ArchLinux's pacman.

[RJ Skerry-Ryan (rryan)]

Found an invalid read/write from AnalyserGain thanks to the hints in your backtrace and valgrind. Fixed in 1.9.x and trunk/1.10 as soon as I merge it. Phlogistique -- please test the 1.9 branch and see if that fixes the crash.

[Phlogistique (noe-rubinstein)]

Fixed it for me.
