Hardware design: List of sensitive GPIO pins, pins which need special care

could you perhaps help me to create a list of GPIO pins, which need some special care during the hardware design?

I think some people reported already some problems with a JTAG pin, if used as output, and I think somewhere also I read, that some USB-FS-PHY pins may have some restrictions if used as outputs. But I do not get it together from my remembering, where I read this.

If some people could share their pin-precautions/ -warnings, best for the STM32F4 parts, that would be great.
