weird things going on in my code

so I've had this snippet of code amongst my 5000 line of code:

Code:

if (root->StmtDomain[1]->type == T_EXPR_ARRAY) 
				{
				isArrayAssign2Array = 1;
				
				isTaNodeForArr2Arr = 1;
				if ( root->StmtDomain[1]->left->type ==  T_EXPR_INTCON && root->StmtDomain[1]->left->type !=  T_EXPR_CHARCON || root->StmtDomain[1]->left->type !=  T_EXPR_VARIABLE 
							|| root->StmtDomain[1]->left->type !=  T_EXPR_ARRAY )
					{ /* do nothing */ }
					else
					{
					isArrayAssign2ArrayWithExpr = 1;
					}
				}

the problem is that whenever I try to run this program and it executes this part of the code, especially the :

Code:

if (root->StmtDomain[1]->type == T_EXPR_ARRAY)

the program just kind of freeze and does nothing

when I change that to :

Code:

if (root->StmtDomain[1]->type == 6)

it progress normally.. T_EXPR_ARRAY here is an element of a struct.. something like this:

Code:

typedef enum{

 T_EXPR_ARRAY
 ............

} ExpType;

Can someone please help me where to look for this? It used to work in the same way like this a few hours ago, however I modified some things and I forgot all of those I did...

That's not an element of a struct, it's an enum. Not the same thing.

Are you sure that's where it's freezing? Either that means one of your pointers is invalid, or it's getting through here and hanging somewhere else. Although changing to 6 wouldn't change that. What does the else look like?

yes I am pretty sure that's where it occurs, at least when I try to remove that block of if statement the program can execute without going on and on... I really don't know how am I suppose to trace this 5k lines of code...

One line at a time.

Alternatively, you can use a debugger of some kind (gdb / Visual studio debugger).

And I don't see anything in the if -- but what about the else? And again, are you sure all your pointers are valid?

yes I am pretty sure.. and I've tried to print stuffs at lines after that.. I've got another conclusion...

when :

root->StmtDomain[1]->type == T_EXPR_ADD then this weird things occur...

It can't really hang inside this if statement; there's three assignment statements and an if. (Well, I shouldn't say it can't; I would say it would be unlikely to.)

That is why we have debuggers! You should never leave home without one.
Visual Studio is, by far, IMHO, the simplest and most powerful debugger there ever was.
