Hi!

I don't know if this is the intended behaviour, but for the following code:

---------------------------------------------------------------------
module main;

void main() {
	for(int i = 0; i < 10; i++) {      // Line 4
	}
	for(int i = 0; i < 10; i++) {
	}
	for(int i = 0; i < 10; i++) {      // Line 8
	}
}
---------------------------------------------------------------------

#####################################################################
Loading symbols from main
->bp main:4
Breakpoint set: main.d:4 0x402014

KERNEL32.dll loaded

        for(int i = 0; i < 10; i++) {
->lsv
Scope: _Dmain
i = 4211075
i = 18
i = 4272652
->
#####################################################################

That is, the "i" variable is shown three times, even though the next two aren't visible yet. If you set a breakpoint in a next line, for example line 8, the "i" variable is also shown three times. I think one "i" should be shown always.

The problem is that I'm integrating ddbg in Descent, and in the varaibles view I use the "lsv" command, so the "i" variable appears three times. A hack would be, if a variable appears many times, send "= i" to the debugger and keep the one with that value, but... if it can be fixed in ddbg, much better.

DMD doesn't emit symbols for scopes below procedure level (bugzilla #1201). therefore Ddbg can't tell which one is the right variable. when evaluating an expression with an ambiguous identifier, Ddbg simply chooses the first instance it comes across.

the last time i checked, MSVC had the same problem. although CodeView provides a solution.
