yes, through ogr2ogr by creating a new file, as you did

It could be either a huuuuge feature whose serialized form exceeds 2GB 
(unlikely, and even more if you convert from an existing flatgeobuf file 
which enforces this limit). Or that you have lots of features and a 
modest amount of RAM. The creation of the spatial index requires an 
amount of RAM proportional to the number of features (maybe 80 bytes or 
so per feature). In this later case, the error message is misleading 
currently. I've just changed it to "ICreateFeature: Memory allocation 
failure" in master.
