Issue ID: 18988 Summary: Reading from unreadable file results in random garbage Product: D Version: D2 Hardware: x86 OS: Windows Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nob...@puremagic.com Reporter: elpenguin...@gmail.com Attempting to read from a file opened only for writing on Windows (10, build 17134, 64-bit) after writing to the file does not throw an exception when read from, nor does it produce a valid result. ``` import std.stdio; void main() { auto x = File("hi", "w"); x.write("Hello."); ubyte[4096] buf; auto slice = x.rawRead(buf); assert(slice.length == 0); //Fails. assert(slice == new ubyte[](slice.length)); //Also fails. } ``` This only occurs when compiled with -m32. -m32mscoff and -m64 throw exceptions as expected. --
