Bug 12781 – process.d: "Executable file not found" is supposed to show executable name but fails

Look at file phobos/std/process.d line ~360, it is the very beginning of function spawnProcessImpl: const(char)[] name = args[0]; if (any!isDirSeparator(name)) { if (!isExecutable(name)) throw new ProcessException(text("Not an executable file: ", name)); } else { name = searchPathFor(name); if (name is null) throw new ProcessException(text("Executable file not found: ", name)); } Look at the "else" clause. If function searchPathFor failed, we are throwing an error "Executable file not found: ", which is supposed to include name of executable file. But name at this moment is null... :-(

Fixed in git head by commit 0812ecd1f6519028070eba0c9b4504bded48a7a5
