There was a problem hiding this comment.
I believe you need to drop "a.out" from the above to make tests work.

@tautschnig I have implemented the fix and it now passes CI. Should be ready to be merged now. |

The changes as such are fine, thanks. Yet could I please ask for the commit message to be amended to answer the “Why?” question? I had to click through three pull requests to even understand what this was good for. And then none of that info will be in the git history. If I have one Christmas wish for this project, it is that everyone reads and adheres to https://chris.beams.io/posts/git-commit/. Happy Holidays! |

@NlightNFotis I'd really like to merge this; please can you sort this out? |

@tautschnig @martin-cs Is the new commit message better? |
|
Thanks a lot for the update! Except for a typo ("teh") that seems perfect. I'll merge once CI completes. |
This extra test is added to ensure that constant arrays, which are known at compile time, do not produce a NONDET instruction to initialise them at the GOTO level, after we use goto-instrument with the --nondet-static flag.

@tautschnig I also fixed the typo. Now it should be okay. |
