AddressSanitizer can not describe address in more detail (wild memory access suspected).

This happens when any option on the main menu (the first one you see when you start the game up) is clicked on. When I use the 'Check for a newer version' button, or the other options which open a web page, the browser and web page are launched successfully (so that bit of code is presumably before the faulty one).

Also, I probably should have mentioned that ASan works by replacing free() and checking its usage.

All looks fine here.
Perhaps it is your openALsoft that has the issue?
