The exception is thrown because it tries to allocate 3435973868 bytes
of memory.

It's hard to tell why, but you can see that it tries to print an
error:

"invalid name "ÌÌÌÌ." in path ""

Where, the path it tried is "ÌÌÌÌ./".

It complains about the "ÌÌÌÌ" not being valid, after prepending
that itself: I think that it prepended it as being the root
(ie, it should be C: or D: or something like that).

That indicates an undefined variable that is being used (the root disk).
Imho, this is a bug in boost - but you might be able to work around
it by actually setting a root.
