Dear Evangelos, I have posted at https://gcc.gnu.org/bugzilla/attachment.cgi?id=35240 a reformatted patch along the Mikael's comment. I have also fixed a failure in the test (parentheses have to be escaped).
The patch fixes not only pr59016, but also pr50259 (there are probably random ICEs?) pr56674 pr58813 pr59024 pr65469 (now marked as duplicate of pr59016). If you confirm the fixes, these PRs should appear in the change log. > PS: It's better if you manage to install DejaGNU, so that you can run > the testsuite yourself. We are already short of manpower. Seconded! I let you address the Mikael's technical comments. Thanks for the work. Dominique
