Bug 22020 – The profile flag does not work in Windows.

I got an error when I ran it with the profile flag on Windows. app.d: ```d /+ dub.sdl: dependency "mir-algorithm" version="~>3.10.60" +/ module app; import std.stdio; import mir.ndslice; void main() { auto s = iota(2, 3, 4); writeln(s); } ``` run: ``` dub run --build=profile --single app.d ``` result: ``` Program exited with code -1073741819 ```

Have you tried running the program without dub, just to make sure this is not a dub failure?

The same thing happened when I ran app.exe as is. I couldn't figure out how to build without using dub. The link between mir-algorithm.lib and mir-core.lib seems to be necessary, and the condition of occurrence is very difficult to understand. Also, I replaced 'iota' with 'sliced' and got the same result. The log for `dub run -v --single --build=profile app.d` looks like this. Some of the logs are in Japanese. ``` PS C:\work\dev\D\sandbox-mir> dub run -v --single --build=profile app.d Using dub registry url 'https://code.dlang.org/' Refreshing local packages (refresh existing: true)...

By the way, when I rewrote the sample code, I was able to reproduce this as well. - If delete the dependency in dub.sdl, it won't reproduced. - If delete import std.stdio and writeln, it won't reproduced. - If delete &arr[0]; in getptr, it won't reproduced. ``` /+ dub.sdl: dependency "mir-algorithm" version="*" +/ import std.stdio; void main() { writeln(getptr(new byte[10])); } byte* getptr(byte[] arr) { return &arr[0]; } ```

I have been informed that this is not reproduced in dmd 2.089.1. https://twitter.com/mattn_jp/status/1405937529090572289 If it is regression, there are three commits that are likely to apply. - https://github.com/dlang/druntime/commit/fe4f3019324ff005049177aabd2e8bf0e3bfeeb1 - https://github.com/dlang/druntime/commit/cf40a3283df44e943bfc37ff2d7e3368d7e0854f - https://github.com/dlang/druntime/commit/0a1de8e35c4a572ff7bb35824b795d102192d30d I think this part is suspicious. https://github.com/dlang/druntime/commit/cf40a3283df44e943bfc37ff2d7e3368d7e0854f#diff-58b0479d390fb9dd50b0b9c04b74e7cb4062af4823f8d52ebcde7cc7cd167ac0L488-R549

I doubt this is beacause using synchronized (via trace_init) before calling rt_init.

I was able to minimize the reproducing code, dub was not involved. app.d: ``` import std.stdio; void main() { auto arr = new byte[10]; writeln(arr); } ``` test.d: ``` module test; struct Test { string msg; } ``` build&run: ``` dmd.exe -lib -of"test.lib" -profile test.d dmd.exe -c -of"app.obj" -profile app.d dmd.exe -of"app.exe" app.obj test.lib app.exe ```

I have encountered this with DMD 2.100.0. It seems to be caused by passing pointers/slices to `std.format`: ``` void main() { import std.format; string x = "%s".format(null); } ``` Run with `dmd -profile -run file.d`. Other flags seem to have no effect.

Further investigation suggests `__equals` may be to blame: ``` int main() { import std.random; // to defeat constant folding auto a = new int[4]; foreach(ref v; a) v = uniform(0, 10); auto b = new int[4]; foreach(ref v; b) v = uniform(0, 10); return cast(int)(a == b); } ``` This is further supported by debugging a faulty binary, with the debugger stopping on the first overload of __equals: https://github.com/dlang/druntime/blob/cf3f7fe/src/core/internal/array/equality.d#L20-L48
