Posted in reply to Jascha Wetzel | Great work!
Another minor glitch - single stepping over a getch() runs to completion (ver. 0.0.4.3)
Impressive fix/release cycle time too. Thanks!

Posted in reply to Sean Kelly | there are a few commands that will not work before the debuggee is running (like dr and ds) - will fix that in the next release.
the symbolic-info-missing error shouldn't show up like an unhandled
exception, will fix that too.
the problem here is, that the link command is missing the -g switch. the
linker won't copy debug symbols from the object files to the exe in that
case.
thanks for the reports!

Posted in reply to Jascha Wetzel | I see a problem when trying to list members of class. The debugger crashes with "Unhandled exception in Ddbg v0.0.4.3 alpha: 4invalid UTF-8 sequence" There aren't any strings in the class, just single element ints, bools & etc. I can't nail it down to a single member since every single member evaluates fine, just when I do a "lsv" does the debugger crash. This brings up a potentially bigger issue I think. Using the D library UTF-8 restrictive routines will cause problem evaluating strings, particularly in Windows Apps. You might want to consider replacing format/sformat/writefln with something that is more forgiving. ------------------------------- Jascha Wetzel wrote: > Ddbg is a Win32 D Debugger > > http://ddbg.mainia.de/releases.html > > This release mainly adds support for type cast and associative arrays. > Type casts can be used to workaround the missing array and enum support > in DMD's debug symbols. |

Posted in reply to dickl | good point about the utf8 routines. i will consider that.
can you email me an exe and ddbg command sequence that produces the unhandled exception?
