I've tried to explain this before, but, as far as I've been able to dete= rmine, the problem doesn't seem to be that a particular test or group of= tests is flaky: the mysterious problems all seem to be related to setti= ng up the test environment. There have been problems, for example, with = files not being found, or the complex pile of patches used to construct = variants on the expected error output not working properly. At least the= unix, windows, ieee, date, oop, primvars, and misc test groups have bee= n affected. Since it's not been easy to reproduce the problem (I've thou= ght it was fixed several times), I have no reason to believe it wouldn't= affect other test groups if we skipped those. An unfortunate consequenc= e of the way the tests are organized, skipping particular test groups me= ans that expected error output is never checked and requires manually ch= oosing the configurations (combinations of compiler/interpreter settings= ) you want to test. I do not see a viable path to fixing the tests for this release, and I d= on't know a way of running a subset of tests that would be both reliable= and meaningful. Other distributions are also skipping these tests. In fact, Guix is currently skipping an unknown (probably large) portion = of these tests because of the issue with "/bin/sh", which has lead to th= ings silently not running. I hope we will get this fixed upstream for the 8.7 release. In fact, I'v= e not yet encountered the problem while building from Git HEAD, but it's= not clear what change might be relevant. (Indeed, the problem might sti= ll be there, and I might just not have hit it yet.) -Philip
