----main.d:
import std.process;
import std.stdio;
void main(){
  writeln(environment["PATH"]);
  system("echo $PATH");
  spawnShell("echo $PATH").wait;
  spawnShell("echo $0").wait;  
}
----
(on OSX if that matters, and I've set my shell to zsh but this isn't the
problem)
export PATH=/usr/bin
path/to/dmd -run path/to/main.d
#this prints:
/usr/bin
/usr/bin
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:... (+ other stuff)
/go/bin
/bin/zsh

The bug is that spawnShell("echo $PATH") should IMO return the same as
system("echo $PATH").

it also changes these (at least on OSX):
MANPATH
SHLVL ( this one is normal though)

I cannot reproduce this on Linux, so it's hard to say what the issue is.  It
would be great if someone else could try this on OSX.

spawnShell() does not touch the environment unless explicitly requested, so I
think the answer lies somewhere else.

It looks almost like spawnShell() starts the shell as a login shell.  In that
case it would read various startup scripts, and re-set PATH along with some
other environment variables.  Could you please run the following commands in a
terminal?

  export PATH=/usr/bin
  $SHELL -c 'echo $PATH'
  $SHELL -l -c 'echo $PATH'

(Note the single quotes, which delay expansion of the PATH variable.)
