What regression bug is the easiest one to start working on for newbies like me?

The others will often say "worked in DMD x.xx and fails with DMD y.yy" where x.xx < y.yy. The idea is then to use digger to determine which change caused the failure: https://github.com/CyberShadow/Digger Just pick any where success/failure is pretty clear and the failing example is clear. Even doing just one will be useful. Thanks! |

If you were referring to actually fixing the regression and not discover the offending PR, then I suggest that you pick one that pinpoints the PR that caused it and try to understand what changes led to it. Once you do that, in most cases, the fix should be straightfoward, by adding a check for the missing bits.

This can help isolate the reasons much faster! Thanks Walter 20484 is mine https://issues.dlang.org/show_bug.cgi?id=20484 I already did the work and found the commit. It is in the initial bug report. Also of note the change inducing the commit was not in the changelog, but should have been. |
