Why timer interrupts are getting enabled?

Hi, I am using P89V51RD2 Micro controller for my project(Which is having 64k Program memory and 1024bytes data RAM and I am programming in C ).I am disabling interrupts (making EA=0)before calling a function and Enabling after comming out from that loop.I am not enabling interrupts in that function but the timer interrupt is getting enabled before comming out from the function,which is making distrubance to the functionality of my system. I feel the reasons for this may be one of the following.
1.I am using Watch dog timer in the code.
2.When I am building the code in keil software it is showing , Program Size: data=9.1 xdata=590 code=44295 creating hex file from "SGW"... "SGW" - 0 Error(s), 6 Warning(s) I think this is because of insufficient internal data memory . can you please tell me what is the reason for this problam?

imterrupts should only be disabled for atomicity issues, not for 'a loop'
