STM32F103 boot loader question

MikeDB

Occasionally I get a crash - I think when stack meets heap in certain circumstances but I'm still working on that and it's not the issue I'm asking about.

The problem is that when the processor crashes I use the boot loader to reload another code build but quite often it then refuses to run and I have to cycle the power on the processor after which it loads and runs the same code properly again. Can anyone suggest what isn't set to default values by the bootloader but is by a power down ? Just worrying this could be an issue in the field if a processor did crash - could the watchdog (not being used yet) fail to recover any problem ?
