You're surely right, I've read about this problem earlier on this 
group and it is probably the reason. But the reason of posting this 
topis was, that I have noticed, that asm entry code seems to be the 
same for 3.3 and 4.0 gcc versions. The difference is location of some 
ISR's local variables on the stack in place, where another function's 
frame is situated. But probalby it is related to an error you have 
described.
