Undefined variables when procedures used in optional arguments

Hello,

I'm not sure if this is expected behavior or not.

Using the following code, if I set a breakpoint in fun1 on line 2 (right before calling fun2) and step through the program after calling fun1 from the CIW, "var1 does not exist" will print.

If I set var1's default value to 1, "var1 does not exist" will NOT print.

If I don't set a breakpoint, "var1 does not exist" will NOT print.

Any direction would be appreciated!

The code:

procedure(fun1()
fun2()
)

procedure(fun2(@optional (var1 fun3()))
when(!boundp('var1) printf("var1 does not exist\n"))
)

procedure(fun3()
1
)

This seems to be an obscure bug with the debugger. If you also put a breakpoint on the when line in fun2, and use continue after the first breakpoint - it works. It seems that single-stepping does execute fun3 (but doesn't step through it) but doesn't bind the variable in the argument list - which is a bit strange.

I'll raise this with R&D (I'll report the CCR number once I've done that).

I filed Cadence Change Request #2977527 for this. It's definitely odd - the optional expression gets evaluated but doesn't get bound to the variable in the argument list.
