All of this might not be a bug at all but an undefined work around for
deficiencies in C++ primitive functions in the avr-gcc support library? To
prevent one from using?
In the early days of avr-gcc, just plain C, not all support primitive functions
were reentrant. If memory serves me, math functions on longs were dangerous.
That not all registers were stacked on entry to the interrupt handler (that
would be costly) and the compiler (and support library) assumed some registers
were free to use without preserving across function calls.
