------- Comment #2 from moritzwarn...@web.de  2009-02-21 19:47 -------
I tried to compile QTD today (http://code.google.com/p/qtd/)
and encountered a problem that a file didn't finished compiling.

After some testing with several dmd versions I found out
that all tested versions before dmd 1.038 work,
but later versions are caught in an infinite loop.
It's the same problem for ldc, but gdc works (old front end version).

The problem can be reproduced with
"dmd -c qt/gui/QPushButton.d -ofqt/gui/QPushButton.o"
and dmd version 1.038 or later (or ldc).

The back trace for ldc looks like this:
(gdb) bt

Looks like Module::imports from module.c is involved.
It was added in dmd 1.038.

Hope that helps. :)
