I'm on v1.03 dev and when I am loading the next day (!) a savegame from Scenario i.e.
"Dynamic Universal War System"
Mission [sp%2fmp]dynamic%20universal%20war%20system.altis
I get always crash tbb4malloc_bi.dll.
This does not happen while I am playing and saving / loading multiple times, it only occurs the next day (so was exiting Arma) and try to continue.
I even started a complete new game and the same happened again.
Thanks to the Community Wiki (http://community.bistudio.com/wiki/ArmA_2:_Custom_Memory_Allocator)
I was able to try different Memory Allocators (tbb3malloc_bi.dll crashed), and onw was able to at least show in Game Picture then freezing (I think it was JEMalloc_bi) and yet antoher is working fine again without crashing:
-malloc=NedMalloc_bi
