Large XMLDocument: Print( XMLPrinter* ) throws std::bad_alloc, XMLDocument::SaveFile does not.

Out of curiosity are you compiling for x86, i.e. 32-bit, targets? It's my understanding that processes run in 32-bit mode are only allowed 2 GB of memory. 1.9 GB is really close to that limit and if you were to have a lot of heap allocated memory elsewhere you can easily go over that limit and the program can't allocate any more.

Since XMLPrinter works entirely in-memory it would need to take up 1.9 GB of memory. Hence, the bad_alloc throw.

Output of file command for my tinyxml2.so:
ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=..., not stripped

It's 64-bit. Same goes for the whole project, which definitely can use more than 2GB of memory.
