Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected.
IMHO, this is a bad programming practice to check for equal and make these assumptions. The code should be corrected to determine the proper size of the bss space and zero accordingly.... or at least test for greater than or equal.
I wholeheartedly agree - I had a similar problem with the command table - The size was correct but the starting point was wrong (again due to alignment issues) so the equal condition was never satisfied. I have always been told than using equals in loop termination conditions is a 'Very Bad Thing'(tm)
