Guard "bound" accesses from Memory Sanitizer checks #225

Closed sugoi1 closed 2 years ago

sugoi1 commented 2 years ago

The Memory Sanitizer creates false positive on the use of thread local storage variables, so this CL adds a setter for the "bound" variable and MSAN guards for both the setter and the getter.

If the root cause https://github.com/google/sanitizers/issues/1409 gets fixed, this and related workarounds can be reverted.
