segfault on vid_restart, dll unloading issue affecting Linux too?
That may be an Unvanquished issue, but this is close to some other issues like:
- https://github.com/DaemonEngine/Daemon/issues/564
and especially this comment: https://github.com/DaemonEngine/Daemon/issues/564#issuecomment-1023785677
and maybe similar to what tried to fix:
- https://github.com/DaemonEngine/Daemon/pull/577
On Linux (Ubuntu 20.04 LTS) I built Unvanquished and Dæmon using the 0.53.0/sync branch. I started the game using dll cgame and sgame, then changed screen resolution which triggered a vid_restart. I got this crash:
Default value '' is not correct for cvar 'cgame.cm_forceTriangles': value "" is not of type 'bool' as expected

I reproduce it everytime on 0.53.0/sync branch when calling vid_restart while a map is loaded, this time on Ubuntu 21.10 (I'm running dll c/sgame):

It crashes there:
const char *CG_TutorialText()
{
playerState_t *ps;
static char text[ MAX_TUTORIAL_TEXT ];
static int refreshBindings = 0;
text[ 0 ] = '\0';
ps = &cg.snap->ps;
if ( refreshBindings == 0 )
{
CG_RefreshBindings();
}
refreshBindings = ( refreshBindings + 1 ) % BINDING_REFRESH_INTERVAL;
if ( !cg.intermissionStarted && !cg.demoPlayback )
{
→ if ( ps->persistant[ PERS_SPECSTATE ] != SPECTATOR_NOT ||
ps->pm_flags & PMF_FOLLOW )
Oh that last thing is an issue with the first frame of RML running too early, before some stuff is initialized.
