Problem mikro c with callig too much subroutines

Hey guys Im working on this code

void subroutine1()
{
//something goes here ( a lot of code )
}
void subroutine2()
{
//something goes here ( also a lot of code)
}
void subroutine()
{
//something goes here too with a lot of code
}

void main()
{
//Configuration bits here etc etc

while(1)
{
if(condition1)
{

if(condition2)
....................{
......................subroutine1();
......................subroutine2();

................................if(condition4)
................................{
................................subroutine3();
................................subroutine1();
................................}

...................}

...................if(condition1)
..................{
...................subroutine1()
...................subroutine3()
..................}

.......}


}

}


Im using the easy pic 7 to download the code to the 18f45k22 . The easy pic do download the code but is not working but if I remove some subroutines it will work with just a few. I dont know if the program counter gets overflowed when calling many subroutines with a lot of code in them and having all this inside IF conditional statement.

Do you know whats happening ? thanks !

Check th stack memory available on your uC. I guss the stack over flow occurs because of too many function calls... And make sure you are not calling any other function calls inside the subroutines...
