The above only diables debug code but does not fix the problem
which is in different place few line below:
if ( pIndex->pArea->fShared && pIndex->fShared )
Should be changed to:
if ( pIndex->pArea->fShared && pIndex->fShared &&
!HB_DIRTYREAD( pIndex->pArea ) )
I'll commit the fix ASAP.
BTW Please remember that using Sx_SetTurbo() (It should be rather called
"dirty read") may cause wrong results when other station update index
concurrently. Do you use some other manual lock mechanism too?
best regards,
