If you install Cbc using [coinbrew](coin-or/coinbrew), then your assumption is correct. We now mirror the MUMPS source because the origin seems to go down frequently. However, when using homebrew, you...

If you want to open an issue at https://github.com/coin-or-tools/homebrew-coinor, we could also consider pointing the homebrew recipe to our mirror.

Either edit the recipe to download from http://coin-or-tools.github.io/ThirdParty-Mumps/ instead of the original download location or build with coinbrew.

Hmm. So I realized that the error being triggered was triggered intentionally and was meant to test the error mechanism itself (see comments in the code). I wasn't expecting such...

> @tkralphs so if I understand you correctly, the current failing of addRows is expected so the current patch on stable/1.17 is OK. Yes, the failure I see when running...

@Mizux Looks like this should fix. Can you verify? Then we can try to get a new release out.
