Yes it's very likely that your problem originates in your own crt0.

Can you verify that the control word generated by your crt0 is IDENTICAL to
the one generated by the standard crt? All bets are that's not the case.

sprintf() works under a number of assumptions about the state of the
run-time. I believe the source code is available, so you can check which
assumptions are those, and whether you comply with them or not.
