Is there an issue I don't know of with variable updates in the debugger?
I had just thought I'd run a line of code,
else
{
trans.depth=-1; //our retrieve did not succeed. we can check this
//field later, and if it's not -1 our retrieve
//succeeded, but we didn't cut, and we can use that
//for move ordering.
//fprintf(logfile,"retrieve failed\n");
}
but, I didn't check that the assignment worked (why would I?).
A few lines later:
0)
So, before stepping throught this line, I go to the debugger window and display the data structure trans. trans.depth was 0. I was irritated, and thought I missed something. prior to resetting the debugger to run by it again, I went to get a drink etc. I come back, about to reset. I _think I checked the variable in the GUI once again. Anyway, on a whim I typed "p trans.depth" into the debugger console... And it came up -1! I brought trans back up in the GUI, and lo, it's -1 now!
What's going on? did the wait trigger it? Was it the "p trans.depth" command? If I'd executed
0)
would it have worked correctly?
obviously, this worries me for a host of reasons!
