Looks like resource leak:

./src/backend/storage/buffer/localbuf.c:    LocalBufferBlockPointers = (Block *) calloc(nbufs, sizeof(Block));

./src/backend/storage/buffer/localbuf.c-    if (!LocalBufferDescriptors || !LocalBufferBlockPointers || !LocalRefCount)
./src/backend/storage/buffer/localbuf.c-        ereport(FATAL,

./src/backend/storage/buffer/localbuf.c-

Two identical pieces of code:
