I am interested to know what that could be.

I guess it can break but remarkably seldom. Everything related to the
startup is in write protected flash and the ram is initialized at
startup from flash so I cannot really imagine what can go wrong.
Usually when a chip starts misbehaving, it is some physical problem,
or the flash is bad and the chip needs to be replaced.

For instance, I had a very strange problem that after power-boot some
random EEPROM bytes were set to 0xff. It turned out that the PIC chip
had a minimum working voltage of 4 Volts, but the brown out reset
detection fuse was configured for 2.2 volts which is only valid for a
low voltage version of the chip.
