Bug 14602 – broken executable if filename contains opDispatch

Consider simplest program: ```d void main() {} ``` Save file as, for example, `issue_with_opDispatch.d`. ``` $ dmd issue_with_opDispatch.d $ issue_with_opDispatch.exe sh.exe": ./issue_with_opDispatch.exe: Bad file number $ rdmd issue_with_opDispatch.d std.process.ProcessException@std\process.d(560): Failed to spawn new process (The requested operation requires elevation.) ---------------- 0x0043770A 0x00429B9E 0x00403F79 0x00403FF3 0x004314B3 0x004313CB 0x00424A4C 0x767B33AA in BaseThreadInitThunk 0x76F19F72 in RtlInitializeExceptionChain 0x76F19F45 in RtlInitializeExceptionChain $ ``` dmd v2.067.1

it works on GNU/Linux, so i think that this is a windows-related issue.

This is a "feature" of Windows operating systems ("Installer Detection Technology" for "User Account Control"). File names that contain the word "patch" (and others, such as "install") will be automatically elevated. https://technet.microsoft.com/en-us/library/cc709628.aspx > Filename includes keywords like "install," "setup," "update," etc. You can disable this behavior locally on your system by using the group policy editor (see link above).
