Consistent Assertion Failures with sound enabled when loading maps in a certain order

[Kieran P]

Ubuntu 11.04 (Classic Gnome Desktop - not unity), ATI 5770 with official proprietary drivers

r9430 (and possibly earlier) Loading the maps in any of these orders causes a consistent and immediate assertion failure. Loading the same map twice does not seem to change anything. It does not cause the error when using -quickstart.

acropolis --> celt-iberia --> death_canyon

celt-iberia --> acropolis --> death_canyon

death_canyon --> celt-iberia --> acropolis

death_canyon --> acropolis --> celt-iberia

[edit] Each of these maps has a different default civ. Civ specific music was recently added (and the new tracks are large).

"Philip`: Mark's error is triggered by the game loading three different music tracks, and probably by them adding up to >20MB, I believe"

Assertion failure. Stack trace is at the bottom. I can't reproduce it if I run './pyrogenesis -quickstart.'

Steps to reproduce: Start game normally. Load Death Canyon. Quit. Load Celt-Iberia. Quit. Load Acropolis. Assertion.

I get the same behaviour. Each of those maps is loading a different music track, each of which is currently about 8MB, so the three of them add up to >20MB (the VFS cache size) which looks suspicious.
