ADDITIONAL SYSTEM INFORMATION :
Should infect all

A DESCRIPTION OF THE PROBLEM :
when len is a large number (2^30), len * 2 / 3 overflows. Should use long to compute intermediate value.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Hard to reproduce, need large memory. Create sufficient thread locals will overflow

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should not overflow
ACTUAL -
Didn't succeed to reproduce because ran out of memory.

CUSTOMER SUBMITTED WORKAROUND :
Don't use too many thread local vars.

FREQUENCY : rarely
