In D, I seem to come accross Access Violations, ALL THE TIME... I never got these so much in C and C++.. I wish I knew what i was always doing wrong, and I try to learn from my mistakes, but it still seems odd to me. are there some common pitfals many of you fall into in developing in D that cause these nasty little errors? Are there more advanced ways to detect the source and more creative ways to avoid them than process of elimination on the back end? I am writing this windows GUI wrapper of sorts, Terra, and it's giving me allot of issues. Are there things I should know about extern(Windows) that I might not be taking into account..? The source will be up on http://svn.dsource.org/projects/terra/downloads/ I appaicate all help, and if you are interested, send me a patch to trevorparscal@hotmail.com Thanks in advance.

Posted in reply to Trevor Parscal | Is an access violation the same thing as a segmentation fault?
Anyway, I used to get a lot of seg faults from forgetting to 'new' a class. To stop this from happening, I use asserts and contracts as follows...
void function(MyClass s)
in
{
assert(s !== null);
}
body
{
// ... etc
}
Also, I use the debuggers backtrace to tell me around the place where my program crashes, and I also use a dose of writef's in debug mode that give me an idea where/what the program is doing. If you are using build, maybe try adding the -full option.
