ols: Fix stack clobbering at start of acquisition 

This off-by-one was clobbering the stack since introduced in a803c0db4d.
However it only set one bit, and that generally appears to have been set
already, so this rarely affected anything. But when it did, it affected
a pointer, causing a segfault.
