Problem with uint64_t and EXTI Callback function

I use the HAL EXTI callback function on an STM32F411 and have made the following strange experience:

When changing data types from float to uint64_t for Efficiency in another callback function (actually from DMA), my EXTI interrupts suddenly stop working. The debugger shows that the EXTI int is pending but the callback function gets not called any more.

Does anybody here have any ideas what is going on here or probably have similar experiences?
