In case it confuses the disassembly, here you can see the inserted
"assert" in my source:
void
DRIDoBlockHandler(int screenNum, pointer blockData,
pointer pTimeout, pointer pReadmask)
{
ScreenPtr pScreen = screenInfo.screens[screenNum];
DRIScreenPrivPtr pDRIPriv = DRI_SCREEN_PRIV(pScreen);
assert( pDRIPriv );
if (pDRIPriv->pDriverInfo->driverSwapMethod == DRI_HIDE_X_CONTEXT) {
/* hide X context by swapping 2D component here */
(*pDRIPriv->pDriverInfo->SwapContext)(pScreen,
DRI_2D_SYNC,
DRI_NO_CONTEXT,
NULL,
DRI_2D_CONTEXT,
pDRIPriv->partial3DContextStore);
}
if (pDRIPriv->windowsTouched)
DRM_SPINUNLOCK(&pDRIPriv->pSAREA->drawable_lock, 1);
pDRIPriv->windowsTouched = FALSE;
DRIUnlock(pScreen);
}
