Hrm..  it sounds as if you are accessing memory with a garbage pointer..
in other words, going outside your array...  And somehow declaring more 
array storage gives more memory so you happen to hit memory which was 
allocated somewhere (probably not for that particular piece of code that 
is accessing it however...)

Could you post the contents of function read_t2?

Thanks,

Sam
