issue only seems to effect linux 64bit, works fine on linux 32bit.
The relevent native code seems to be inside
LWJGL > src > native > common > org_lwjgl_openal_ALC10.c
The code in there is some serious voodoo magic, not even gonna attempt to mess with it
SVN shows that only two changes were made to this file after the 2.7.1 release (one
2 months ago, another
6 weeks ago). Seems about the time the issue was reported, so might be a possible cause. Could any of those changes be relevant to such an issue?
