Modify the source, and add an AL_PRINT() statement to the start of 
ALSANoMMapProc, before the while() loop. If you do that, it may also be a good 
idea to add a counter, using a uint64_t. eg..

uint64_t myin64val = 0;
...
aluMixData(...);
myin64val += data->size;
AL_PRINT("Current val: 0x%llx\n", myint64val);

and see what the value is when it starts giving problems. If it's very close 
to 80000000 or 100000000, then it very likely is an overflow problem 
somewhere.
