 We recently have found a crash issue related to this function in
 greg_month.cpp.

 the block from line 39 is not thread safe. If multiple threads call this
 function simultaneously, it will lead to a crash. As one thread is
 populating the map while the other thread may start using the map, or even
 worse two threads populate the map at the same time.
