You can first verify the stabs in the ELF file using avr-objdump -G.
Watch out the SLINE records.

Did you properly use .function/.endfunc?

Also, i found that avr-gdb gets completely confused if there are
globally visible symbols inside assembler functions.  It's IMHO best
to use completely local symbols for assembler jump targets.  Either
use Unix (AT&T) assembler style local labels (just a small integer
number only, can be re-used inside the file, reference gets a `f' or
`b' appended to indicate the jump direction), or start the label with
".L".
