STM32L051 Port PH1 Initialization Error

I used STM32CubeMX to generate code for a STM32L051R8xx microcomputer.  All I/O ports initialize correctly except PH1.  If I delete the PH1 initialization code, the program executes correctly.  With the PH1 code the microcomputer resets when it attempts to initialize PH1 as  a push-pull output.  This error occurs for code that uses either HAL or LL code.  Is there a bug in the silicon or very low level firmware?
