Subject: [committed] testsuite: Add testcases for already fixed PR [PR100541]
Date: Wed, 2 Mar 2022 10:42:28 +0100 [thread overview]
Message-ID: <Yh88BET3oQX3Rpmt@tucnak> (raw)
Hi!
These testcases started failing with r12-630 and one of them
got fixed with r12-4531 (aka PR102764 fix and r12-4616 further
improved the fix) and the other went latent in r12-2591 (i.e. threader
changes) and I believe was fixed for real by the PR102764 fix too.
Regtested on x86_64-linux and i686-linux, committed to trunk as obvious.
