[PIC] PIC starts assigning random values to variables when program is lengthy

[burrow]

Hey iam working on a project with PIC18F4520. and iam using mikroc to write the program.
The program is really lengthy and it uses around 44% of the ROM. and now i am in a problem, When The rom crosses around 43 or 44% then the pic starts assigning random values to certain variables.

Ya i checked if the problem is with any newly added block of code, but its not.

It's surely not the PIC doing wrong, it's either the compiler or your own code.

Are you using any kind of code-size limited compiler demo version?

Iam using full version of mikroc 6.4

Are you saying that:

unsigned char x;
x=0x00;

will make x some random value or are you trying to rely on the compiler to set all your variables to 0x00 and some are and some are random?

Good programming practice would be to set the variables to a value in code rather than hoping the compiler does it for you.
