digitalmars.D - Weird ouput when using dub / dmd with vscode terminal

reply Aldo <aldocd4 outlook.com> writes:
Hello,

I have a strange bug on my laptop at work when working with 
VSCode and the integrated terminal. At home it is working 
perfectly.

When I type dub in the terminal (powershell, bash or cmd) the 
process hangs before the end and display weird output. Today I 
typed 'dmd -v' and this one crash as well (sometimes displaying a 
big error messagebox and sometimes "ERROR: This is a compiler 
bug.".

No problem with LDC2, no problems with dmd/dub at home.

What version of DMD are you using on your work laptop?

The problem is that the official DMD executable for Windows is built with an old and outdated linker known as optlink. Just build DMD yourself using ldc2 or just use ldc2 instead. This issue already been reported and a pull request that fixed the issue was made, but no action has been taken on D's management end.

I will try that, thanks. This bug really need to be fixed asap for the sake of user experience.

I agree, the burden falls on the few people that have the VMs that make all the release builds to update the environment accordingly for Windows. But they don't seem to have any interest in doing the work.

This has nothing to do with Optlink. Nor the release environment. It is a bug either in dmd or in snn (dmc's libc). ``` fputs(("---\n" ~ "ERROR: This is a compiler bug.\n" ~ "Please report it via https://issues.dlang.org/enter_bug.cgi\n" ~ "with, preferably, a reduced, reproducible example and the information below.\n" ~ "DustMite (https://github.com/CyberShadow/DustMite/wiki) can help with the reduction.\n" ~ "---\n").ptr, stream); ``` Only the first two lines are printing, as it is a CTFE concatenated string that is rather concerning.

Optlink is the only linker that uses OMF libs and DMC's std library (both DMC and Optlink are outdated and bit rotten), so it is an Optlink only issue. That's not including other issues and limitations caused by Optlink.

The issue with the VM environment that builds the compiler is that it doesn't have ldc2 installed ;).
