Test-case: ----- void main(); ----- $ dmd -run test.d DMD v2.066 DEBUG OPTLINK (R) for Win32 Release 8.00.13 Copyright (C) Digital Mars 1989-2010 All rights reserved. http://www.digitalmars.com/ctg/optlink.html OPTLINK : Warning 23: No Stack OPTLINK : Warning 134: No Start Address --------------------------- Unsupported 16-Bit Application --------------------------- The program or feature "\??\C:\dev\code\d_code\test.exe" cannot start or run due to incompatibity with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available. Now let's try with /NOEXECUTABLE: $ dmd -L/NOEXECUTABLE -run test.d Same crash. The problem (as I see it) is that OPTLINK creates a warning when a start address is missing, rather than an error, so /NOEXECUTABLE has no effect.
Crash? That doesn't look like a crash.
(In reply to comment #1) > Crash? That doesn't look like a crash. Well it's a dialog box, isn't it? And it's completely uninformative to what the real problem is. The problem is Optlink generates an empty .exe file even if you use /DELEXECUTABLE.
