With the option "-split" the code of line 274 must be executed.
The error was due to a failure in the flow control that executed the code of line 262.

Fixes #1556

@fperdigon are you intending to merge into master or into poq_issue_1507_progress?

Your branch was developed from another baseline branch (poq_issue_1507_progress).
If master, could you try to rebase your branch (having a single commit) on top of the master branch?

This should work with:

git fetch
git rebase --onto origin/master origin/poq_issue_1507_progress fperdigon_issue1556
git push origin fperdigon_issue1556 --force

Thanks!

Just making sure that we won't make this before knowing the intent.

[fperdigon]

sorry, my mistake

[jcohenadad]

as discussed in SCT meeting @fperdigon please:

• start from master branch

[fperdigon]

Hollo @zougloub please a little help here. I ran the commands you told me and now a lot of commits that are not mine appear

[zougloub]

You did the right thing : only one commit from the master base. Only github wasn't aware of that yet. I changed the base and now github is happy too.

[fperdigon]

Yes, sure it was github web interface issue, now everything looks good, thanks @zougloub
