No, as far as I know the modern Altera FPGAs are pretty forgiving with power sequencing. And even there, at worst it would lead to some startup problems, it shouldn't cause a short on some VCC pins. I'm sorry but if there indeed isn't any overshoot of some power lines at startup I don't see what could cause this.

Are you sure the short is in the FPGA itself and not the LDO or a filter between them?
