[avr-gcc-list] How to determine which interrupt fired?

[Rick Mann]

I have a simple app that only defines the UART0 receive interrupt  
handler for an ATmega128. I can set that it's getting called in gdb  
(and because its code is executing), but then something happens and  
my code jumps to the top of main. I'm assuming some other interrupt/ 
reset is occurring, but I can't figure out what it is.

Any suggestions on how I can determine this? Thanks!
