OK thanks, is the code I attached here OK?  I already submitted this to Atmel
also (#605725).  Last time I submitted a bug to them this is the reply I got
back:

Note that avr-gcc and avr-libC are open-source projects, which you may directly
report bugs
to (see http://www.nongnu.org/avr-libc/bugs.html).



(In reply to comment #5)
 Marking this bug as INVALID because the AVR Toolchain 3.0.0.207 is not an
 officially released toolchain, and only in beta.
 
 If you have any potential bugs, then please send to avr AT atmel DOT com, and
 please CC me. AFAIK, Atmel did not (or should have not) sent you to here. 
 
 When you do send a bug report, send a compilable test case that shows the bugs
 along with the command line you used, and especially show which device this is
 for.

Why isn't this a bug in the interrupt handler?

What is beta AVR toolchain 3.0.0.207 btw?  We do not release such, so
maybe you should file a bug with the vendor releasing that?

It's not a bug in the handler since when the interrupt fires at the point when
the stack pointer is invalid (right after 0x50c), the program counter gets
pushed onto the stack, which is an invalid location.

When I tried to submit a report with the vendor, they pointed me back here. 
Maybe this should go to AVRLiBC?
