Is there system clock error in STM32F030?

Is there something wrong in mbed (MBED_LIBRARY_VERSION 108) for STM32F030 clock? When I using wait(1.0f), it is six times faster. I tested it in NUCLEO-F030R8 board and STM32F030-Disco board, get same result.

It is not fast in old mbed version (MBED_LIBRARY_VERSION 88).

In recent revisions, the STM32F030 went from being totally broken, to flashing the LED in a blinky program 6x faster as you have witnessed. Reported here: https://github.com/mbedmicro/mbed/issues/1329
