+Subject: [PATCH] Use explicit typecast to size_t
+
+maxMemoryUsageBytes is size_t type which may not match long long value
+internalDocumentSourceGroupMaxMemoryBytes.load() returns, so typecast it
+to avoid narrowing warning from clang
+
+document_source_group.cpp:378:22: error: non-constant-expression cannot be narrowed from type 'long long' to 'size_t' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]
+                     maxMemoryUsageBytes ? *maxMemoryUsageBytes
