Comment 4 for bug 1775497

Thank you very much.

malloc(): unsorted double linked list corrupted

Happens if you have writen over the borders of a memory region allocated on the heap but not pass the borders of the page, leading to a real "segmentation fault". The issue here is that the crash is a symptom of a access violation that has happened before.

Can you install the debug symbols and try to reproduce a real segfault?

If you are using our ppa, you can install it via

Adding

deb http://ppa.launchpad.net/mixxx/mixxxbetas/ubuntu YOUR_UBUNTU_VERSION_HERE main/debug

to

/etc/apt/sources.list.d/mixxx-ubuntu-mixxxbetas-YOUR_UBUNTU_VERSION_HERE.list

sudo apt-get update
sudo apt-get install mixxx-dbgsym

Else you may build mixxx from source
