--- Comment #3 from Kostya Serebryany <[email protected]> ---
r184928 disables the instrumentation of AllocaInstr with alignment more than
the redzone size (i.e. > 32)

This is a workaround, not a full fix. 
Full fix will require to create 256-byte redzones for 256-aligned allocas,
which in turn requires more expensive redzone (un)poisoning. 
Since this is an extremely rare case, I am not planing any work on it in near
future. 

I'll close this bug now, the larger problem is tracked at 
http://code.google.com/p/address-sanitizer/issues/detail?id=8
