--- Comment #14 from Zdenek Sojka <zsojka at seznam dot cz> --- Thank you all for looking into this! I can't provide testcases for other issues, if they exist at all, since I am hitting the first one too often. If you fix only the first issue, there is a chance the other "broken" patterns will be hit in the future; if such a testcase exists at all.
