Bug 9059 – No exception runtime error message with missing file + byLine

import std.stdio: File; void main() { auto f = File("missing").byLine(); } If I compile and run this program with dmd 2.061alpha with "-g" it correctly gives a stack trace (with no line numbers): dmd -g -run test.d std.exception.ErrnoException@std\stdio.d(315): Cannot open file `missing' in mode `rb' (No such file or direct ory) ---------------- 0x00412F44 in char[][] core.sys.windows.stacktrace.StackTrace.trace() 0x00412DCF in core.sys.windows.stacktrace.StackTrace core.sys.windows.stacktrace.StackTrace.__ctor() 0x00404D2F in D3std9exception80__T12errnoEnforceTPOS4core4Çâ¬c5Ôio6_+bufVAyaa11_7374645c²696f2e¨Vk315ZÇÄ-FÇÜ-L Çâ-ZÇ܃ 0x004045DC in extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void runMa in() 0x00404612 in extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void runAl l() 0x00404229 in _d_run_main 0x00402D04 in main 0x7782D309 in BaseThreadInitThunk 0x77A51603 in RtlInitializeExceptionChain 0x77A515D6 in RtlInitializeExceptionChain ---------------- If I compile and run it without "-g" (dmd -run test.d) it doesn't show the std.exception.ErrnoException, and the program just crashes with no error messages at run-time. Maybe this is a regression.

Works now. Probably connected with Issue 8083. Will not close as source reason is unknown.

Works for me, too. It's unlikely someone will try to figure out why it wasn't working two years ago.
