Follow-up Comment #1:

As you already noticed, the function prologue/epilogue
handling is not part of avr-libc.  It's part of GCC.

So please report this to GCC's bugzilla.

Was this issue ever resolved?  I find no mention of it at

I think my message to the list was the last mention of it.

It certainly seems like a serious bug, but I'm puzzled as to why it's occurring. The gcc code I looked at appeared to be correct.

I've cc'd(and followups) the avr-gcc list on the slight chance that there's someone there that isn't on the libc list.
