          Issue ID: 17278
           Summary: [ICE] dmd 2.075 segfaults on error in implicitly
                    imported module
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

=== main.d ===
import second;
XPixmap[1] tilexpm;
void loadTileImages () {
  tilexpm = XPixmap();
}
===

=== second.d ===
struct XRefCount(T) {
  this (this) { doIncRef; }
}
alias XPixmap = XRefCount!XlibPixmap;
struct XlibPixmap {}
===

"dmd main.d" segfaults:
doIncRef
zsh: segmentation fault  dmd main.d

but: "dmd main.d second.d" gives the proper error message: second.d(2): Error: undefined identifier 'doIncRef'
