I think both work. ;) I think you need to tell your DBGer to break on AssertExceptions, (or whatever they're called) but I don't know if that is feasable... -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

I'd look at String.d line 1568 <g>.

String.d is something like char charAt(int index) { return str[index]; // ok, probably not utf-8 compatible. // I'm just getting aware of utf-8. } double <g> to you :) any way thanks, I've been know for overlooking the simplest things... I know this is an old issue. I'm sorry for repeating but D needs better debugging capabilities. I could have in { assert(index<str.length); } but I don't see the point... Ant

Add the following line: if (index >= str.length) *(char*)0=0; before the return statement. Compile with -g. Run it in the debugger, and you should get a stack trace.

it's there, thank you. (but now I can't reproduce the error, grrr! It's was compiling the Miguel's code example (compiling from leds of course), but no longer...) Ant

You might want to look at Ares. One of the first things I did was to hook the assert error routine. It should be trivial to put code in there to either grab the stack or alert the debugger immediately rather than throwing an exception. Sean

thank you, I'll take a look. but... where is it? there is no project on dsource. Ant

Yeah, what I'm calling "Ares" is actually the result of some experimentation I've been doing. It's available at: http://home.f4.ca/sean/d/ares.zip The Ares project itself doesn't have an SVN location yet because development hadn't gotten that far when interest waned. Sean

Try "break exit".  It puts a breakpoint on the "exit" function.

Better later than never. ;) (I guess "break exit" is a command for gdb?) Wow, that's reviving an old thread! No one had posted in this thread since Novemember 2004... http://www.digitalmars.com/d/archives/digitalmars/D/13108.html
