I produced a patch to fix the issue, complete with test-case. I am attaching it here, but I will also submit it upstream. It would help, in the meantime, if it was applied downstream too.

The attachment "Patch to fix the problem" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

@Matteo do you plan to propose a debdiff?

@Matteo can you please check the above debdiff and the build ongoing on ppa:costamagnagianfranco/costamagnagianfranco-ppa?

Thanks Gianfranco, the package you provided does not crash anymore for me.

@LocutusOfBorg: Mind backporting this fix also to xenial?
The diff between 3.5.1 and 3.5.2 looks small enough to not cause any regressions: https://cmake.org/Bug/view_all_bug_page.php?filter=161388

I'm working on porting kodi's build system to cmake and we're and affected by this.

lets ask for a sponsor then!

Hello Matteo, or anyone else affected,

Accepted cmake into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/cmake/3.5.1-1ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

cmake updated!

so far so good

@Christian please double check!

@LocutusOfBorg: Confirming, the fix works. Thanks!

Just for reference, for my usecase (building Kodi), I would have preferred an update to CMake 3.5.2. Then I could simply have checked for the CMake version 3.5.1 in the build scripts and opt out directly with an error informing that 3.5.1 is not supported and devs have to update to at least 3.5.2. Now 3.5.1 will work on Ubuntu, but won't work on other distributions (except if they also carry that downstream patch along). But I guess this is simply how the Ubuntu release strategy works.

Well, I'm not sure updating cmake to a new minor release in a stable Ubuntu LTS is worth the effort...

I admit I was tempted, but too many packages relies on it, and I think before upgrading we should at least do an archive rebuild just to check everything still builds.

For sure cherry-picking a patch is the safest way to fix the bug, but I admit I would have upgraded cmake with not many issues (the debdiff is not scary)

@LocutusOfBorg: Most important is that the bug is resolved. I don't know what it takes to get the full stack compile tested with a newer version. But you're probably right and it's better to play safe here.
