I'm not sure if this is a bug or even a legal assignment, but the following

Compiling with v0.101 on Windows 2000 with flags -inline -O gives:

Internal error: ..\ztc\cod2.c 4207

I just started using D and am a bit rusty with the old c/c++ skills, let alone
knowing how to do things proper in D, but I'm quite excited to learn... :)  I
have been following the NG for a while now and let me say, Walter, fantastic
language!  I've learned so much (just about programming and language design in
general) from everyone who posts; I was quite happy just reading, but I've
decided to join the fray. :P

Looking forward to sharpening my D skills and letting some others get a bit
rustier! (not by avoidance of course, just ramping up the D usage) :)

Every internal error is a bug.  Or, at least, every internal error 
that's reproducible.

What were you expecting it to do?

It seems that getcwd() has a an extra character in the string in returns.  I
can't tell what it is, but I was trying to remove it.  As for the assignment, I
didn't know if I needed to size the array first or if I could attempt the above,
so I just went for it.

Debug question: How would I find out what that character is using a printf type
debug technique.  (I've never used gdb or similar debuggers in windows/unix
before).  Thanks for the help!

This isn't quite on-topic but when I last tried std.file.getcwd it returned 
a string with a superfluous space at the end. I guess this is why you're 
trying to create a sliced string. I suggest this

    getcwd[0 .. length - 1]

Yup, that's spot on what I was attempting.  Thanks for the tip.

So the corrected code is simply:

char[] curdir;
curdir ~= getcwd()[0 .. length -1];

or:

char[] curdir;
curdir = getcwd()[0 .. length -1];

or:

char[] curdir;
curdir = getcwd();
curdir.length = curdir.length - 1;
